Proposal

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

Deleted in 1:1 chat expense remains in LHN with the receive's name changed to the email

What is the root cause of that problem?

When the user B deletes a message, for user A the reportAction is deleted but the lastMessageText and lastVisibleActionCreated of the report is not updated. Due to this, when the expense is deleted and the updated last visible action is a ADD_COMMENT, the LHN shows lastMessageText and the report is shown as unread which is incorrect as it shows stale data

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

For LHN text:

The LHN text based on the last report is handled by getLastMessageTextForReport which will fallback to report.lastMessageText for report actions like ADD_COMMENT as they don't have any special handling

When lastOriginalReportAction is a deleted action, we should fallback to getReportLastMessage(reportID).lastMessageText which will find the lastMessageText based on the last visible action

we already do this for closed report action so we just need to add a or condition for our case.

App/src/libs/OptionsListUtils.ts

Lines 732 to 734 in f49f6c4

	if (reportID && !isArchivedReport(reportNameValuePairs) && report.lastActionType === CONST.REPORT.ACTIONS.TYPE.CLOSED) {
	return lastMessageTextFromReport || (getReportLastMessage(reportID).lastMessageText ?? '');
	}

so the updated code will be

    if (reportID && !isArchivedReport(reportNameValuePairs) && (isDeletedAction(lastOriginalReportAction) || report.lastActionType === CONST.REPORT.ACTIONS.TYPE.CLOSED)) {
        return lastMessageTextFromReport || (getReportLastMessage(reportID).lastMessageText ?? '');
    }

For read/unread highlight

The unread highlight is handled by isUnread() which gets lastVisibleActionCreated from getReportLastVisibleActionCreated. We can update getReportLastVisibleActionCreated to use report actions whenever possible

function getReportLastVisibleActionCreated(report: OnyxEntry<Report>, oneTransactionThreadReport: OnyxEntry<Report>) {
    const lastVisibleReportActionCreated = getLastVisibleActionReportActionsUtils(report?.reportID)?.created ?? report?.lastVisibleActionCreated ?? ''
    const lastVisibleActionCreated =
        (oneTransactionThreadReport?.lastVisibleActionCreated ?? '') > lastVisibleReportActionCreated
            ? oneTransactionThreadReport?.lastVisibleActionCreated
            : lastVisibleReportActionCreated;

    return lastVisibleActionCreated;
}

What specific scenarios should we cover in automated tests to prevent reintroducing this issue in the future?

Test getReportLastVisibleActionCreated and getLastMessageTextForReport return correct values when there is a deleted report action

What alternative solutions did you explore? (Optional)

@jaydamani's proposal makes sense to me, I tested it and it works well.
