Proposal

Please re-state the problem that we are trying to solve in this issue.

The LHN shows removed 1 user instead of left the chat when leaving a thread.

What is the root cause of that problem?

Leaving a thread will add a LEAVEROOM action from the BE response.

And that's considered as a room change log action.

App/src/libs/SidebarUtils.ts

Lines 351 to 375 in 4622e19

	} else if (ReportActionsUtils.isRoomChangeLogAction(lastAction)) {
	const lastActionOriginalMessage = lastAction?.actionName ? ReportActionsUtils.getOriginalMessage(lastAction) : null;
	const targetAccountIDs = lastActionOriginalMessage?.targetAccountIDs ?? [];
	const targetAccountIDsLength = targetAccountIDs.length !== 0 ? targetAccountIDs.length : report.lastMessageHtml?.match(/<mention-user[^>]*><\/mention-user>/g)?.length ?? 0;
	const verb =
	lastActionName === CONST.REPORT.ACTIONS.TYPE.ROOM_CHANGE_LOG.INVITE_TO_ROOM || lastActionName === CONST.REPORT.ACTIONS.TYPE.POLICY_CHANGE_LOG.INVITE_TO_ROOM
	? Localize.translate(preferredLocale, 'workspace.invite.invited')
	: Localize.translate(preferredLocale, 'workspace.invite.removed');
	const users = Localize.translate(preferredLocale, targetAccountIDsLength > 1 ? 'workspace.invite.users' : 'workspace.invite.user');
	result.alternateText = `${lastActorDisplayName} ${verb} ${targetAccountIDsLength} ${users}`.trim();
	const roomName = lastActionOriginalMessage?.roomName ?? '';
	if (roomName) {
	const preposition =
	lastAction.actionName === CONST.REPORT.ACTIONS.TYPE.ROOM_CHANGE_LOG.INVITE_TO_ROOM || lastAction.actionName === CONST.REPORT.ACTIONS.TYPE.POLICY_CHANGE_LOG.INVITE_TO_ROOM
	? ` ${Localize.translate(preferredLocale, 'workspace.invite.to')}`
	: ` ${Localize.translate(preferredLocale, 'workspace.invite.from')}`;
	result.alternateText += `${preposition} ${roomName}`;
	}
	if (lastActionName === CONST.REPORT.ACTIONS.TYPE.ROOM_CHANGE_LOG.UPDATE_ROOM_DESCRIPTION) {
	result.alternateText = `${lastActorDisplayName} ${Localize.translate(preferredLocale, 'roomChangeLog.updateRoomDescription')} ${
	lastActionOriginalMessage?.description
	}`.trim();
	}
	} else if (lastAction?.actionName === CONST.REPORT.ACTIONS.TYPE.POLICY_CHANGE_LOG.LEAVE_POLICY) {

Because the action is not an invited action, the removed message is being used.

What changes do you think we should make in order to solve the problem?

We can make sure the room change log condition is only true if it's not a thread.
ReportActionsUtils.isRoomChangeLogAction(lastAction) && !result.isThread.

This way, the last message of the thread report will be used, that is, left the chat.

What alternative solutions did you explore? (Optional)

We can improve the room change log message by adding the case for the leave room that returns left the chat (and it's translation). Currently, it only handles invite, remove, and update description.

Proposal

Please re-state the problem that we are trying to solve in this issue.

Thread in LHN displays "removed 1 user" after leaving thread.

What is the root cause of that problem?

In the past, we moved to this case if the report action is invite or removed action. See the diff here for more details.

Now, we use isRoomChangeLogAction function that checks whether the action is a room change log action or not and it's not correct with the previous check. And then when we leave the room, the last action is LEAVEROOM action, and removed 1 user appears.

What changes do you think we should make in order to solve the problem?

We should create a new function like isInviteOrRemovedAction that will return true if the report action is one of four action types that we used in the past here.

function isInviteOrRemovedAction(reportAction: OnyxInputOrEntry<ReportAction>): reportAction is ReportAction<ValueOf<typeof CONST.REPORT.ACTIONS.TYPE.POLICY_CHANGE_LOG | typeof CONST.REPORT.ACTIONS.TYPE.ROOM_CHANGE_LOG>> {
    return isActionOfType(reportAction, CONST.REPORT.ACTIONS.TYPE.ROOM_CHANGE_LOG.INVITE_TO_ROOM, CONST.REPORT.ACTIONS.TYPE.ROOM_CHANGE_LOG.REMOVE_FROM_ROOM, CONST.REPORT.ACTIONS.TYPE.POLICY_CHANGE_LOG.INVITE_TO_ROOM, CONST.REPORT.ACTIONS.TYPE.POLICY_CHANGE_LOG.REMOVE_FROM_ROOM);
}

And then use this function here to update the condition correctly
