Apply modifiers to an animation and export as fbx?

I recently viewed a tutorial on YouTube: “Roll-Up Animation in Blender”:

I’ve been trying to export this to .fbx for use in Unreal Engine? I was able to export the animation without the modifiers. I also was able to apply a Morph Target instead of a timeline animation, but again I cant get both to export. I cant get the modifiers with the morph targets together.

This file has a keyframerollanim.blend (519 KB) animation rollanim.blend (519 KB).
This file is using a morph target for the animation rollanim morph target.blend (519 KB).
