Config protection policy to share with a third-party app only

Hi all,
I want to share a document from Teams via third-party app only (Ex: Telegram). I configure Teams using Intune app protection policies.
I tried sending to config Send org data to other apps, and using Policy managed apps with Open-In/Share filtering. 
Config Select apps to exempt with Telegram appID and app name but not work.

I want to ask if this approach is correct and if Microsoft allows us to do that?
Thanks.
