This could be user error here, but i'm not seeing the app get added to intune after creation.
Tried with both 1.2.0 and 1.2.1 alpha
To recreate:
Search for app
Check app
Ensure tenant ID/clientID and redirect are populated.
Press connect.
365 login window shows . Authenticate.
Returns to app and app details are cleared and the app isnt listed in intune.
Does it need winget-install in the same folder as the exe?
