Description:

I like to push apps script via github action. I found this example but don't understand how the login works. What is CLASP_CREDENTIALS ans how is it generated? I tried several things like Workload Identity Federation or just generate a oauth key. But the problem is that there gets open a credential page or things like a 'client_id' is missing.
