Question VFX Graph Ghost of Tsushima leaf effect

I'm trying to get particles to react to an object once it's move and then fade out. I've searched and read everything I could find on this. However, I just can't get it right.

This is the main tutorial I was using to sort this out.

This is effectively what I'm trying to get to work.

I figured I'd set velocity and angle in the "select" area but doing so only effects them while they are within the sphere then they immediately stop once they leave the "select" area. So I tried curves but I just can't get this to react how I want it to.

Thanks!

Here's a cleaned up graph where it sort of "works".
