Unable to generate .aar file when we refer AndroidX Libraries

Steps to Reproduce

Create an Android Library Project in Visual Studio 2019 add Xamarin.AndroidX.AppCompat 12.0.6 from Nuget Packages
Add an Android activity that needs to called from Native App to this Library project
Set the Activity Class attributes as [Activity(Label = "LibActivity"), Register("com.company.droidxlib.LibActivity")], to make this visible in Java Android.
Build the Library Project to generate your assembly (.dll) file
To build .aar file use Embeddinator script in Terminal as shown below. mono /Users/myname/.nuget/packages/Embeddinator-4000/0.4.0/tools/Embeddinator-4000.exe '/Users/myname/Projects/DroidXApp/DroidXLib/bin/debug/com.company.droidxlib.dll' --gen=Java --platform=Android --outdir='/Users/myname/Projects/DroidXApp/DroidXLib/output_Android' -c

Expected Behavior

It works fine and Embeddinator generated .aar file, when I use Xamarin.Android.Support.v7.AppCompat 28.0.0.3 with Android Library Project.
I have used the following command to generate .aar file

Actual Behavior

However, when I tried the same by adding Xamarin.AndroidX.AppCompat 12.0.6 it gives the following error.
