Blender to Unity: Blendshape/ shape keys import


I applied shape keys to my object wanting to make an animation in Unity. But, when I import the object into Unity, it doesnt import the shape keys.

I was checking out this video, and followed its steps, but I do not get an option for “Skinned Mesh Renderer” which has the blendshape within it.

Here is my file. The mesh was originally imported via STL if that makes any difference or helps with figuring out why it didnt work. Thanks for any help
