android sample app logs INVALID_CERT_HASH when trying to log-in via Apple

Logs:

getRecentTasks: taskId=1234   userId=0   baseIntent=Intent { act=android.intent.action.MAIN flag=268435456 cmp=ComponentInfo{com.mmk.kmpauth.sample/com.mmk.kmpauth.sample.MainActivity} }
[GetAuthDomainTask] Error getting project config. Failed with INVALID_CERT_HASH 400
Error Result: There was an error while trying to get your package certificate hash.

Not sure what cert it shows error for. Similar error in my app [GetAuthDomainTask] Error getting project config. Failed with INVALID_CERT_HASH 400

okay so my guess here is that sample app was signed by the key which is not included in repo, so when I try to log in it shows cert error. but the it is very strange that it works with Google sign in

solved it by adding cert hash in Firebase Project Settings > General > Your Apps > SHA certificate fingerprints

cert hash can befound by gradle signingreport

I weill keep this open since Apple login fails in the sample app...
