If you want to see how I create my HeyGen videos you can watch me in this video replay.
I had a tech issues between my video software and the YouTube Studio setup which messed up with giving you the correct link that I posted yesterday. When I restarted my recording about 20 minutes in I also forgot to turn on my mic feed until about 1:30 into this video so, if you scroll up to about 2 minutes into it you can watch the rest of the video.
