How can I use a script to get a manifest.m3u8 file for Fox station feeds?

[Oldfart1234]

If you go to https://www.foxlocal.com/ you can view live programming from Fox network channels in several major U.S. cities. They are shown as tiles and if you click on a tile, for example New York, it takes you to the local station's site such as https://www.fox5ny.com/ and a window near the top of the screen starts playing the stream. If you then bring up your browser's "Web developer tools" and enter m3u8 in the search box (network tab) and refresh the page, it will show a manifest.m3u8 link and then several rendition.m3u8 links. if your right click on the manifest.m3u8 link and copy it, and then open VLC and open that link as a network stream (and if you are quick enough doing that, since those links apparently have a very short expiration) it will play in VLC as long as you don't stop the stream or there is no network interruption, etc. If the stream is stopped for any reason then you have to repeat the process, starting with re-getting the manifest.m3u8 link.

I think the link changes every couple minutes or so but somehow VLC (and the web player) seem to be able to follow along once you start the stream using the manifest.m3u8 file. However, I don't want to watch it in VLC, I want to use it as an input for Tvheadend. In order to do that I need to find some way to get that m3u8 link using a script of some kind, and in order for it to be useful in Tvheadend that script cannot depend on a web browser being installed, because Tvheadend runs in a Docker container on a server that has no desktop installed. I thought about Selenium but that would require a desktop environment and web browser to be present, and also I have never had great luck with Selenium; maybe it's just that I don't know how to use it but when I tried to use it in the past it was very unreliable.

So my question is, is there any way to get the m3u8 link using curl, wget, or some other Linux tool(s)? What would really be great is if there were a program that could get that link from the page url, start the stream (and restart it if it gets interrupted) and then make it available on a local port, so that Tvheadend could always go to the same address (such as localhostort), but if such a program doesn't exist I can still make it work (I think) as long as I can get the m3u8 link, in that case the only thing I can't do is automatically restart the stream if it gets interrupted, but that should not be an issue 99% of the time.

I'm hoping there might be a way to do this from a script, so any help would be very much appreciated!
