How do I upload development build to Google Play Games?

Hi, I’m trying to implement Firebase(Ultimate Mobile Kit by ) in my project so I can authenticate users with a Google Play account.

While trying to do that, I found out I should link my google play service to both development build and distribution build. However, when I package and upload development build, Google Play rejects it, saying it contains a debuggable apk.

It’s obvious I’m missing something but hours of googling didn’t get me anywhere. I found this( but didn’t really help solving the problem.

Can someone provide me with step-by-step instructions on how to upload a development build on Google Play?

I’m wondering the same, trying to troubleshoot why my leaderboard isn’t working but how can I do that when I can’t have development build in google play, and I can’t log in to google play ( to get access to leaderboard ) if I don’t upload APK, so what am I supposed to do? <.<
