Give it to the youtube-dl tool ( Download).

(The youtube-dl tool can also find the m3u8 tool automatically some time give it a direct link to the webpage where the video is being displayed.) It might have an m3u8 extension that you can type into the Filter. There is always one, as that's how it works.
