Fear of getting rejected as an “App Aggregator”

I’m developing an app where I need to stream around 15 videos of 5-6 minutes each. These videos will be uploaded on Google Firebase and will be streamed via link on my app. The app will have more functionality than these videos but these videos will be the USP of my app. The videos are wholly owned, recorded and edited by me and no one else. Will sharing links result in app rejection? Especially if they’re uploaded on “Google” firebase. And if not, how do I prove to apple that those videos are my property.
