After you publish the app on Play Store, Google signs it and the Google app signing key certificate needs to be registered in the project's Firebase console for it to work. After you publish the app, in the Play Console, under Release, click on Settings. Click on App Integrity. Click on the App Signing tab. Copy the SHA-1 fingerprint to your clipboard. Go to your Firebase Console and select your project. To the right of Project Overview, click the gear icon and select Project Settings. Under Your Apps, click on your Android app and enter the SHA-1 fingerprint that you copied from the App Signing tab.
