Request: offer conversion of AAB to APK for Android apps, too

**Is your feature request related to a problem? Please describe.**
If we generate AAB file to be used by devices right in them, it's impossible. Each person who gets the "AAB" file needs to use this tool to convert the app into APK file.
I know AAB isn't intended to be used for this purpose of sharing apps installations, but that's the nearest thing we can do to simulate installation from the Play Store, without the Play Store.

**Describe the solution you'd like**
A way to use this tool on Android OS itself, to convert the AAB file into APK file, to be installed&run on it, just as if it was from the Play Store.
All this without the use of a PC to make a special solution for this specific device.
If this is already possible and by the rules of the Play Store, please let me know.

**Describe alternatives you've considered**
Of course, instead of exporting to AAB file, the IDE allows to export to APK, but then you lose the entire testing of the AAB file, because split APK files are supposed to install only a part of what's inside the AAB file.

**Additional context**
It could be nice to even install the AAB file directly on the device (without the help of a PC and USB), without conversion.
