It then gives them the role and adds their Discord user ID and ULB email adress to a database. The user will is then automatically verified on every server that the bot is running. The bot also has a rename functionality (optional, per server), names are extracted from the email adress.

-This forces a total update of the database and of all the servers. Since the bot already does this automatically at startup and after each reconnection, the only normal usecase for this would be if you manually add an entry (server or user) to the google sheet instead of using the `/user add` command above, we don't recommend manually editing the google sheet.
