Um I’m not even sure how to do that???
Much less I don’t have a way to be able to note it as I have absolutely nothing on that phone…(I’m currently on a different phone noting this)

From the top down menu it should have screen record built in & you could find it here.
I’ll give it a try & see if I can get it here somehow? No guarantees tho
When theres a will you'll find the way. The file upload in amethyst should be fine.
If you need to edit a video not sure how well these are but.
