What is Games App ID

So I’m trying to configure my project for release and there is thing in Google play services tab called “Games App ID”.
For some reason there is my Sender ID entered and I don’t think it should be there. Where to get correct App ID?
Its written that it should be obtained from developer console but I can’t find anything there

I found App ID in Firebase console but once I enter it into project settings UE says its invalid, but what I noticed is that it consists of Sender ID and other stuff. So is Sender ID = App ID?
