https://imgur.com/a/Hs9gX5WI'm looking for a free a bit more advanced screen recorder /without an watermark/ and when I get a free time on a PC I'll help you out with the guide. Maybe I can cut off the video to a small pieces and make a step-by-step gifs which you can use embed here

You could use OBS (Open Broadcaster Software) Studio. Its open source and thats what most streamers use when they are online and streaming. Im not fully familiar but Im sure its one of the best video recording softwares in the internet. And of course, its
free.
