AGP Upgrade Assistant window not opening in Android Studio

Question

When I press Tools > AGP Upgrade Assistant button, nothing happens.

I am using Arctic Fox 2020.3.1 Patch 4. I also tried this on Bumblebee 2021.1.1 and the same problem occurs.

Other maybe relevant info

Fluter Android Studio plugin 63.2.1
Dart Android Studio plugin 203.8452
Dart 2.15.1
Flutter 2.8.1
Android gradle plugin 3.6.0
Gradle 6.1.1-all

Answer 1

The AGP Upgrade Assistant opens only when you open the Android folder as an Android project

Answer 2

As HWK's answer you should open Tools---> Flutter ---> Open Android module in Android Studio

It will open another window which opens the Android folder as in the below image.
