Hide unused bones like SKM_Manny_Simple

Hi,

I’ve created my own rigs using the Manny and Manny simple method and using the default UE5 skeleton for my custom character. I’ve noticed that for my character the unused bones are still visible in the editor but they are not being used.

There is an option to show only weighted bones from the Skeleton Tree but I cant do the same for the preview.
Did I do something wrong with the import or rigging process? The extra bones I did not weight on my custom character so makes sense why they are greyed out.
