I have a problem with new product model. I want to create a example product with graphql

I have a shopify plus and the read_users permisisons. Via graphql I’m able to retrieve a bunch of data from my staff member like name and such. Unfortunately, I can’t find a way to fetch the user role the staff member is assigned to. Another problem I have is that I’m not able to query the staff member list, every field I try, I get an error saying that “query” is not recognized. So my questions are:

I need some help with the GraphQL Admin API with creating a product with options or variants that have stock.
