There was another suggestion over on r/techsupport (https://www.reddit.com/r/techsupport/comments/mze1pa/any_idea_what_kind_of_cord_i_need_to_get_video/gw095ld/?utm_source=reddit&utm_medium=web2x&context=3) and I'm hoping between both of your suggestions, I get one that works. Cords are something I can almost always find a use for sooner or later, so I ordered the following:

My hope is that at least one of these works. I'll update you whenever I get them / get around to trying them out!
