First I should report I have lodged an issue with Glaxnimate here:
I turned my screen recording into a walk through with a voiceover (I wouldn’t call it a tutorial). There may be errors (and let me know if there are please), but I think it is reasonably self explanatory and should get the job done.
P.S I have since turned the mouse highlighter, mouse click indicator, and zoom features on in my recording software, so next time I won’t have to do the work in Shotcut, but it was fun anyway!
