Can't see "My Registries" window after i implement Firebase Scoped Registry!

After I implement the Google LLC Scoped Registry with the URL: "https://unityregistry-pa.googleapis.com" and Scope "com.google" to connect unity to Firebase, i cannot see the "My Registries" window, which is needed to implement Firebase Authentication and all the firebase Referrences. I tried doing this on multiple LTS versions of Unity like 2020.3.5f1, 2020.3.3f1, 2020.3.15f2, and even 2020.1.17f1. Still nothing. I managed to find the "My Registries" window in 2020.3.3f1 once a few months ago, but now i can't get it to work. My "google-services.json" file is correct so that is not the problem. Also i get the Warining "File C:\Users\MyName.android\repositories.cfg could not be loaded. System.Threading.ThreadHelper:ThreadStart ()"

to get the bug-- start a firebase app and try with this tutorial that i followed "https://www.youtube.com/watch?v=yAtDDcLuj4k&t=50s"
