Custom Scroll Animation

How can I create custom animations on entrance/hover/loop?

Wix Studio Editor

I’d like to create a custom animation on scroll/entrance or even loop. This should be my clients logos automatically scrolling and loop. I’ve been able to do this correctly with the “click” option but the others only seem to have presets where this isn’t possible, am I missing something?

I have tried using this for click but I wish for custom animations to just appear without action ideally.
