Help, Can’t access videos from R2

Hi.
My domain got limited due to video streaming served on the website. So I want to move to R2. But unfortunately all videos ( actually my videos is not MP4, its TS for working with my m3u8 which also server from my site) from R2 that being accessed from custom domain are being served with an error:

This video has been restricted . Streaming video from Cloudflare’s basic service is a violation of the Terms of Service. Please visit cfl.re/tos to learn more.

I have seen others who have had similar problem and finally solved it, is there anyone who can help me?
