Megscan tree need to be modified.

Requesting a help on below query.

I need to download a tree model from Mega Scan, such as the European Beech, along with its materials, textures, and wind animation. I want to export it to Maya, apply the textures, and make some adjustments to the mesh, like adding a branch. Afterward, I’d like to export the modified tree, along with its animation, back to Unreal Engine 5. Could you please let me know if this process is possible and provide guidance on how to accomplish it?
Adding a link for the same below.
