Google cloud integration

I'm trying to make connections to accounts in Google  cloud for manage accounts but I'm not sure what requirements we need... User permissions? Anything special?
Do I have to use a SCIM type connector for each system since there are no native connectors?
I don't know if it will be necessary to activate something in Google  cloud.

Please, does anyone who has made this connection or recommend any kind of documentation to explain it?

thanks
