Google login: How do I update my OAuth flow?

[mj72]

I got a mail:
"Update your OAuth flow - to use compliant redirect URIs and Javascript origins. To meet OAuth URI validation rules before September 13, 2021".

Should I change something in:
/members/check_google.php

Or change something in:
https://console.cloud.google.com/apis/c ... ls/consent

?

Thanks a lot...
