Scopes for a custom social connection

Hi Dear Community

I’m creating two custom social connections, each one to GMail, i configured all required settings

Authorization URL

Token URL

i tried many formats to send the scopes openid email profile, but also received error messag at moment to authenticate

Error 400: invalid_scope

Some requested scopes were invalid. {invalid=[openid%20profile%20email]}

The reason to use custom social connection instead of GMail Social connection or Google Workspace Enterprise Conneciton is that this options are not included on free plan
