Android 'Games App ID'

Where in the ‘Google Play Console’ can I find the ‘Games App ID’?
I thought it was the reverse domain name (com.yourcompany.yourapp) but when I do that unreal shows a massage with (The game app id you provided is invalid|).

In this video I see that they use a number, where do they get it from?

Google Play Console >> Game Services >> [Click on your app] >> [Game ID under app name at top].

[ID is 12 numbers]

Yep, that’s it, thank you for the answer!

in the “new” Google Play Console >> Settings >> Manage game projects >> under Active projects sections, Game ID are shown under app name in the list of Game Project
