Unable to update Mixamo Animation to a Rigged character

Question

We have Rigged character(.glb) need to add Mixamo Animations to it.

I uploaded the .glb file into Blender and exported the same from Blender as .fbx file

Then i uploaded .fbx file into Mixamo as new character and added the required animation to it.
Then i downloaded the character as .fbx file. Still i could not see the updated animations.

Pls suggest using Mixamo how can i add custom animations to my rigged character.

Thanks vij
