Bypass Error When Creating Account With Existing OAuth Email

Suppose user first uses email/pass for log in using xyz@gmail.com, few month later on decides to use google oauth2 with same xyz@gmail.com

(or in reverse order)

but appwrite will prevent this saying user already exist, is there any way to overcome this?

why needed: sometime user forgets password and quickly want to login using oauth2

This isn't the intended behavior

https://appwrite.io/docs/references/cloud/client-web/account#createOAuth2Session

...the server will attempt to look for a user with the same email address as the email received from the OAuth2 provider and attach the new session to the existing user. If no matching user is found - the server will create a new user.
