When a user opens the Mirror dialog but their account’s content access does not include any categories in the selected workspace, the destination category dropdown appears empty or the Mirror action stays disabled, with no explanation shown to the user.

Suggested Enhancement: Display an inline message in the Mirror dialog when no destination categories are available to the current user, stating that their content access does not currently include any categories they can mirror into, and directing them to a project Owner or Admin for access.

Benefit: Users immediately understand why they can’t proceed and know the correct next step, instead of assuming the feature is broken and repeating the same failed attempt.
