Character too small when importing into editor

Alright, so I imported an astronaut character I made in Mixamo, and tried to import it into UE4 so I could retarget the Mannequin’s skeleton to use with my astronaut. However, when I imported it into UE4, it said that the bones were too small to create a physics asset. And indeed when I looked in Persona the character was incredibly tiny. Is there any way that I may be able to have the character as the size of the starting mannequin, using the animations as well?

Well I don’t have an idea about the scaling in Mixamo but in blender just see this vid

I scale up to 100 times
