Setting up the Google SignIn or SignUp

Hi, I am new to softr. I am building An AI-powered community app for real estate investors to network, and build relationships and partnerships on real estate off-market projects. Making them feel like valued members of an exclusive club.

I’d like them to sign up via a google signin or signup. How do I set that up? I followed the Knowledge base notes - to set this up
"To enable Google Sign In on the Signup and Sign In forms, you first need to integrate Google Sign In by adding Google App Client ID and Secret credentials here.

Can someone please put me through the steps how to get this done? I am kind of stuck at the project setting up on google cloud platform
