User deleted in the application but not in the database - Reactivate

Hello, a user was removed from OJS 3.3.0-14. The question is that now I want to recreate the same user, with the same e-mail address, and from OJS it is not possible. How can I reactivate that user in the application?
Deleting it from the database and recreating it, as I understand, is not advisable.
Thank you.
