How to attach weapon to right hand of my rig imported from blender?

I have a nice humanoid model with rigify rigging imported from blender.

I’m able to also import my saved animation “actions” from blender to unity.

I also have few plain weapon models that I want to attach to the right hand of my humanoid and also have the ability to rotate it having the humanoid hand as a pivot.

Is this accomplishable or I do have to have a whole new humanoid model for each weapon (which would look quite ugly…)

thanks

Attach the weapon under the wrist bone in the hierarchy?
