Scraping and downloading M4S Segmented Audio & Video Files

Question

My school refers students to watch lectures on this short course platform. To access them, certain credentials have to be entered. Videos are embedded as GoolPlayer, with Flowplayer.js script used and they don't give the option to download the videos.

This is a link to the video (need to copy and paste it, clicking it won't work): https://www.gool.co.il/%D7%94%D7%A0%D7%93%D7%A1%D7%90%D7%99%D7%9D-%D7%AA%D7%9C-%D7%90%D7%91%D7%99%D7%91/%D7%94%D7%A0%D7%93%D7%A1%D7%90%D7%99-%D7%90%D7%93%D7%A8%D7%99%D7%9B%D7%9C%D7%95%D7%AA-%D7%95%D7%A2%D7%99%D7%A6%D7%95%D7%91-%D7%A4%D7%A0%D7%99%D7%9D/%D7%A1%D7%98%D7%98%D7%99%D7%A7%D7%94-~~%D7%A1%D7%95%D7%92%D7%A8%D7%99%D7%99%D7%9D2~~%D7%9E%D7%9B%D7%A0%D7%99%D7%A7%D7%94-%D7%94%D7%A0%D7%93%D7%A1%D7%99%D7%AA~~%D7%A1%D7%95%D7%92%D7%A8%D7%99%D7%99%D7%9D1~~/%D7%9E%D7%91%D7%95%D7%90-%D7%9C%D7%A1%D7%98%D7%98%D7%99%D7%A7%D7%94-(%D7%9E%D7%9B%D7%A0%D7%99%D7%A7%D7%94-%D7%94%D7%A0%D7%93%D7%A1%D7%99%D7%AA)#77794

Observing the network in Chrome, you can find chunks of the video and audio split into segnments, with request url as such:

I have tried quite a few chrome and firefox extensions to try and download the videos without any luck. Also tried a few M4S scripts on github.

The best thing I found that did do that trick was InviDownloader, an opensource program, BUT, can't seem to grab all segments because of the files name, it changes in a random order, so the program can only grab the first and last one.

Any thoughts or ideas on how can the video be downloaded?
