Importing/retargeting Mixamo animations to my Rigify rigged model

I just finished rigging my characters using Blender’s Rigify addon. However, i would like to “import” some of the Mixamo animations i have downloaded to this model i just finished rigging. I could use Mixamo’s autorigger, but then i would lose all the Rigify bone structure and the amazing tools it creates. Basically, i’m planning to use Mixamo’s animations as a base, so i can tweak and improve upon then.

Is there a way of retargeting or importing animations in Blender? Can you guys share a technique for this?
