Delete third party filament in UP Studio 3

How can be deleted third party filament in Studio 3 ?

I am sorry, I did not mean UP Studio 3. It is clear in Studio 3. I was referring to WAND. Thanks.

To delete a material from wand, make sure the material is not the one currently selected and choose edit from the drop down list. Click the X to move the material to the right hand list. Then close wand and open again and it should be gone.

Correct. Thanks a lot.
