Play Games Services Server-Side API Access sample

[teksal]

I'm trying to implement the Java example shown here with Nodejs using the client libraries. My server runs as a Cloud Run Service. I've tried several variations of the samples shown here, but they all ended up Invalid Credentials error.

Required credentials are all set up in Play Console, the Android client can login to Games Services, can get the authCode as shown here, pass that code to server, and I could not figure out how to proceed after that. I just want to verify this player on the server, calling applications.verify() method.
