how to properly export my character from blender to mixamo to apply animation I downloaded a character from mixamo and then in blender edit some changes in character but when i export the character in FBX and try to upload the character on mixamo it won't let me upload

I can't figure out what I am doing wrong
this is my character

I added the exo suit is it because of that?
solved it ! it turns out I had too many vertices in my model by decimating the mesh it got uploaded and perfectly rigged
Go to edit mode
Mesh-&gt;cleanUp-&gt;Decimate Geometry
decrease the ratio to reduce mesh size
