Hey @abdul hakeem
TOTP configurations are 6-digit codes. If you're being asked for 6-digit code, then that code is in the Authenticator app. However, even though your email is gmail.com, the 6-digit code should be a workplace account rather than personal in your Authenticator app. If you don't have the workplace account configured in Authenticator, then you'll need to reach out to the Teams admin to assist you in resetting your verification methods. The https://aka.ms/mfasetup won't do you any good if you don't have access to a configured and verified sign-in method.
