However, I would like to enable passwordless sign-in using Microsoft Authenticator, which I can't seem to get to work or enabled when signing in to my on-premise applications such as SharePoint and Exchange OWA published via WAP 2019. If I login to any other service in Azure, then it works.

How do I enable it in my ADFS?
