Why is there no Juju Watkins merch/apparel?

Can someone please explain why there's no official apparel for Juju? I really want a shirt with her in her USC jersey with her iconic hairstyle on a shirt. The only thing I've found is a magazine cover shirt from Slam Media and that's not what I want.

Was it like this for Clark too? I just find it odd that she's not selling apparel and cashing in in it through NIL.

I think I'm going to have to make my own custom shirt, but I'd rather purchase an officially licensed product to ensure she gets some profit.

Once theory I made up was that her Nike contract might prohibit her ability to sell merch, but again I just made that idea up.

Anyone have insight into this?
