shoot, I cant figure it out, tried clicking on everything, looks like it might have wirked but ...not:(

If it didn't work then try this, on your phone as the video is playing, press down on the video until a download window pops up. Sometimes it takes a few tries, my phone is old. It works on my Brave browser, perhaps on other browsers too(?) It then saves it to your browser's download storage, which should show up in your phone's download file. I've never tried this from a computer. Hope this helps!
