Restricting Access to Private Videos

I have a Pro Glide app to which I want to upload custom video content for the app’s users. Am open to uploading the video on google drive or youtube. The app is restricted through a email whitelist which is how I can ensure that only users of my app have access to the video content. But how do I make sure that they don’t share the video with others by copying and sharing the link (youtube or google drive). Has anyone encountered this issue and does anyone have ideas, thoughts on how I can restrict access.

If you’re using email whitelist anyway and your videos are also on google drive, you might be able to simply whitelist the videos in your drive to the same list.

It’s double the effort but very simple.

Also does YouTube not have a private channel option where again you could duplicate the same whitelist?
