Remove a comment permanently
Delete (permanent) – Row action Delete (or "Delete permanently") removes the comment from the database. A confirmation drawer or dialog may ask you to confirm. After confirm, the comment is deleted and the row disappears from the grid. Use with care; deletion is usually irreversible.
Trash vs Delete – Trash moves the comment to Trash (recoverable); Delete permanently removes it. So "Trash" for moderation, "Delete" when you're sure you don't need it.
