How do I enable Glasses in a custom content Hat? [Solved]

Sorry if this is the wrong place to ask.

I am looking for a way to modify an existing custom content (a hijab mod by LumiaLoverSim) to allow it to be worn with glasses. Strictlyfor personal use as I am trying to make my gf. She's wearing hijab and glasses.

I've tried re-categorizing it as hats and even earrings but it doesn't seem to work. Glasses will disappear if my created sim try to don the hijab.

Is there any setting that I am missing to adjust?

Edit: Nevermind, I think the easiest way to get this done is by exporting the mesh, and import it into a new hat mesh like princess leia mesh.
