ServiceDesk Plus hosted through Azure app proxy - mobile app login issue

With v14850, SDP supports Azure Application Proxy (with pre-authentication).

However, login attempts with the Android mobile app (v6.0.4) result in the following error:

"Azure pre-authentication details are not configured in the application. Please contact your administrator."

Error: Azure pre-auth not configured

The documentation around this appears incomplete, missing, or unclear.

Could anyone provide guidance on what configuration needs to be added and where?

Thank you.
