How to get the AnimationTrack of the Walk Animation in the Animate Script

In my game, to change a player’s walk animation, I do it like so from the server:

char.Animate.walk.WalkAnim.AnimationId = "rbxassetid://YOURANIMATIONID"
char.Animate.run.RunAnim.AnimationId = "rbxassetid://YOURANIMATIONID"

How can I get the AnimationTrack instance so I can use the GetMarkerReachedSignal method?

I’ve tried messing around in the Animate script under the player’s character, but I can’t find the reference to the new animation, only to the old.
It does actually change the animation visually.

But where is the new AnimationTrack created when configureAnimationsSetOld is run?

I’ll have to take a better look at this in the morning, brain is fried. Hopefully I find it then
