Question

Hi everyone I was wondering something about the 3rd party + email recipe let s say someone uses google signin and then tries to signup using the same email address I notice that in the database there are 2 users created with the same email and different userids ofcourse is it possible to configure supertokens to prevent that I would like to use the email as user id and when the user tries to signup with the same gmail address to get an error about they are being already registered
