My Flutter App got reject from Apple Review stating this 5.2 Intellectual Property (5.2.3)

My App got reject from Apple Review stating this (AUG/2020)

I'm using the youtube data api v3 to get the popular videos bycountry and display as a list in the app (App built using Flutter &include other content tabs too). each list item displaying only thetitle, description, thumbnail image and upload date. when click onlist item to stream the video I launch in youtube app. (no steamingin my app). but apple reject my app stating "Guideline 5.2.3"

Guideline 5.2.3 - Legal

5.2.3 Audio/Video Downloading: Apps should not facilitate illegal file sharing or include the ability to save, convert, or download mediafrom third-party sources (e.g. Apple Music, YouTube, SoundCloud,Vimeo, etc.) without explicit authorization from those sources.Streaming of audio/video content may also violate Terms of Use, so besure to check before your app accesses those services. Documentationmust be provided upon request.Next Steps

To resolve this issue, please attach documentary evidence in the AppReview Information section in App Store Connect evidencing that youhave all necessary rights or permissions to the third-party audio orvideo streaming, catalogs, and discovery services in your app.

I'm not sure which document to upload to pass the apple review or how to resolve this issue.

also In my app i'm not streaming any videos, only redirecting to youtube app. I'm not sure it's violate Terms of Use,

Thanks.
