Need advice on app preview videos

Hey! So I literally am just now finding out that you can put videos on your App Store listing (I’m not really a professional dev so I’m learning stuff as I go) and I wanted to get people’s advice on how to make it engaging! Right now, I have a placeholder that’s a pretty basic screen recording of me running though the app, but I wanted to see if there were any tools I could use or specific things to focus on (definitely down to learn how to edit too)!

Here’s the page so you can get an idea of what I’m dealing with here. I’d love to see what you guys think I should prioritize/cut out. I’ve also been curious about App Store ads but I have noooo idea how that works and I’m working with a pretty low budget haha
