PMs and Designers collaboration

I just want to know how designers and pms are placed in a company?

Because where I work I feel the PM is really dumb and she doesn't understand ux or even a bit a sense of visual design on how ui should work. She says "I don't really care how a button looks as long as it's there on the page".

And I keep her in loop for feedbacks and she just doesn't understand the problem statement. Initially I thought maybe I'm not explaining it correctly but it's almost a year now and I feel she's dumb.

She's actually a friend of the CEO so she agrees to whatever he says and he's kind of similar so I don't really know what to say.

Also, I always work on a new project without having a PRD in place. So again is that how it's supposed to go where I do the PMs job and a product designers job or how is it?

Any comments or thoughts are appreciated 🙏
