How to import a mesh deformation animation from Maya?

Hello, I’ll try to explain what I want :

I have my rigged character, it also has lots of blendshapes for deformation. For my animations I just import them without mesh and use my main Skeleton.

Now I have created another animation where the mesh deforms using faces and soft selection. How can I make it work inside UE?
I export my mesh, check animation, bake animation frames and then I import it inside UE but animation doesnt play.

Which is the correct way for doing this? I dont want to create more blendshapes for this and, if its possible, I want to keep using my original Skeleton and mesh.

Thanks in advance!
