Is it possible to Live stream an "Unknown sources" ?

Hi ! 

While trying our app, I've seen that I can't stream our app on Facebook or other platform. I have a message like "The developer seams not have allow live stream" but when I check the settings for sharing the app, the live stream is enabled. Is it a features working only with application allow in the Oculus Store and not with "Unknown sources" ?

The application is running on Oculus Quest.
Capturing photos and vidéo and stream the app on Oculus app are working fine.
