How to get Upload key in Android Studio

Appflow
1

Build failed with “Not enrolled in App Signing”. So I have to generate an Upload Key in Android Studio. The instructions say

In the menu bar, click Build > Generate Signed Bundle/APK.

This Menu element in Build seems to only show if a project is loaded. I don’t manage to load my Ionic Cordova project into Android Studio. Is there a way to do it?

Thanks for this!
It doesn’t answer my question: how to load an ionic project into Android Studio?
However, I found the solution: Open a new project. It takes about 20 minutes to load but then you get the correct link under “Build”.
