two-factor authentication method

[JackieLong11]

A friend of mine accidentally set his phone number as the authentication method for my Zoom account. But now I can't contact him. The Gmail account and the Zoom account are both mine. Currently I can't login because there is no code.
So is there any way I can delete his phone number
Experts please support me. Thank you
