How can I use a m3u8 url in stream?

I currently use a platform on my website that encodes the transmissions to hls and throws me a link with the m3u8 file
but I don’t know how to use that url in cloudflare’s stream platform.
the url is like this
http: // (mydomain) /3_.m3u8
the url does work in the player and in the browser, but in cloudflare it tells me error:
Invalid URL (Code: 10010)
Please can you help me.

Stream is an end to end product which does the storage and encoding/packaging. You can upload video files such as MP4s but not encoded and packaged videos (m3u8s) since Stream produces the m3u8 itself when you upload mp4 files.
