https://developers.google.com/api-client-library/java/google-oauth-java-client/setup

has a link that says

Also see the ProGuard setup instructions that are part of the Google HTTP Client Library for Java documentation.

But it takes you here https://googleapis.github.io/google-http-java-client/setup.html#proguard and theres no mention of proguard.

I'm using

implementation("com.google.api-client:google-api-client:2.0.0")
implementation("com.google.oauth-client:google-oauth-client-jetty:1.34.1")
implementation("com.google.apis:google-api-services-calendar:v3-rev20220715-2.0.0")

so if anyone know the proguard rules I need for a desktop app that'd be helpful. Or just fixing the link I guess? First time using proguard on desktop so im a bit out of my depth.
