Hello ! I've a Supabase DB created with other developer, and someone of them (not in my team now) as created User Enum. But, now, I'm not unable to see or edit these UserEnum data. Someone who know how to update these data ? Thanks !

This looks like a type the developer created using SQL, you can read more about creating, renaming and updating types in the Postgres docs https://www.postgresql.org/docs/current/sql-altertype.html

This is what I think, but the only think is in my SQL editor, I can't see the SQL request :/

If the developer did it on their account or by using the database credentials and connecting directly to the database then doing it from there it will not show in your SQL editor.
