Skeletal mesh animation import from Blender

Hello everyone, I followed this tutorial https://youtu.be/dSziSB9LDig?si=zENT0NvjO3C2WXcV and I made a single bone linked to a cube and I’ve animated the bone to rotate 180 degrees.
The animation is done using Nonlinear Animation panel in Blender.
Once I import inside Unreal the scale is fine, the skeletal mesh and the cube mesh are there but the animation is only showing the cube not moving at all.

Any suggestion?

Thank you
