Where to find docs of UWP apps for app-to-app communication?

Question

Microsoft Universal Windows Platform enables two-way app-to-app communications using the method Luncher.LaunchUriForResultAsync as described here.

The following Windows apps declare the property ReturnResults in their manifests as "always":

• Microsoft.WindowsCamera_8wekyb3d8bbwe
• Microsoft.Windows.Photos_8wekyb3d8bbwe

The following ones declare it as "optional":

• Microsoft.People_8wekyb3d8bbwe
• Microsoft.WindowsMaps_8wekyb3d8bbwe
• Microsoft.Microsoft3DViewer_8wekyb3d8bbwe
• Microsoft.MixedReality.Portal_8wekyb3d8bbwe
• microsoft.windowscommunicationsapps_8wekyb3d8bbwe
• Microsoft.Windows.ParentalControls_cw5n1h2txyewy

This means, these apps are able te respond when called by other ones using the mehtod LaunchUriForResultsAsync.

Where can one find any kind of doc/references of their input/output parameters?

I searched all the microsoft docs websites, google, github, stackoverflow but to no avail!

We suggest use LaunchUriAsync method to launch them with parameter. and LaunchUriForResultsAsync is internal using. Currently, we have no such document for that. If you do want this doc please feel free post your requirement in UserVoice.
