Deactivate Twitter opened with Apple

I opened my twitter account today going through Apple they showed in Home Screen. Never asked me for a password.

I'm trying to deactivate my account so I can make 1 the conventional way adding email and password. I press deactivate, and it ask for a password. I try my Apple password, but says it not valid. I can’t deactivate this account but there must be away. Called Apple Tech but they didn’t know. I signed in with apple so I don’t have a password to give them. TWITTER doesn’t have anything in their help center.
