Google Play Billing Vs Google play games billing , how to avoid google play games workflow ?

Hello Everyone, i have an application on google play, in new system only “games“ can have Game app id, and if it is not game (i.e category is App), google play games section disappear, i.e (no game app id no longer exist).

In Unreal project, i have enabled Google Play support , left Game App Id empty, Entered the license key, and disabled admob section, although when calling ShowExternalUI it always popup Google Play Games Login.

My question how to work based on Google Play Billing (IAP) workflow, i see Unreal doesn’t differentiate between both billing systems in documentation.

and it always lead to Invalid player UniqueNetId.

It only work if i converted app to “Game“ in category, and set Game App id, License key, and connected app with clould play games project and set Play Games Outh Client id which is totally (Google Play Games ) Work flow , not (Google Play) normal workflow, so what to do now , should i just buy , or make my own native plugin ?

Using UE 5.7.3

Thanks in advance,
