M series Mac - TestFlight does not show Install option for iPad app on MxMac

Our users install our iPad app on their M1 macs from AppStore. But, when we build the TestFlight app, I was expecting TestFlight would show Install button for iPad app. But it doesn't. Still, it shows it requires M1 mac. Our users are on M1 mac. Still, no button to install.

I don't see an option to add macOS app in TestFlight (please see first image)

Can someone please help?
