How to publish a .Net application to the Windows Store targeting ARM?

Question

Reproduce like this:

1. Create a WPF application targeting .Net 6.0 .
2. Add a packaging project, add the WPF application as its "Applications", and associate with an app in the Store.
3. Try publishing targeting ARM in both.

This is the exception I get:

The specified RuntimeIdentifier 'win-arm32' is not recognized.
