How can I convert an apk to aab in app inventor?

[gkamp]

I tried to upload an app to Google PlayStore and it asks me to upload an APK or an Android App Bundle File that has been signed with a key which is also used to sign the APKs delivered to users. How can i this be done in the app inventor?

APK signing with Google Play

The easiest way to get around these questions / problems is not to use "Google Play App Signing" as you apparently did before. Otherwise this question would have arisen long ago. I have also used "Google Play App Signing" on some of my apps and have to be very careful every time I want to release these apps.
