Google Play: How test in App Reviews before launch

Hi, i’m going to release a little game on Play Store, but i’ve been trying to get the In App Review system for days, without success.

Currently, the game is on Internal Test status, so, i don’t know if the game have to be on production status for the showing the App Review API UI, orm aybe i did some wrong.

The code is very simple, the same code than a lot of tutorials uses, and should work.

How do you know if the App Review API is working ok on your games before launch it to Production status?

Ok, can autoreply me.
For somebody having the same problem: Be careful on Play Console, don’t check “Decide myself when changes are applied”. The game was “stuck” until i’ve accepted the description, icon, etc… chagnes.
Once the game is on the store available for testers, In App Reviews start working.
