Custom dashboard for products

I want to try to setup axelor for our product information department to use to keep track of all of the products that our company sells, with the goal of being able to create an internal parts catalog that we can send out to our franchises for reference to be able to order inventory. We would not be using the axelor software for inventory management, sales, or purchases, it would only be used to create a source of truth information database so multiple spreadsheets maintained by multiple people wouldn’t be how they do things anymore.

How would I go about doing this so someone setup as a regular user with the product role that I will create so they can log into a custom dashboard just for products so they do not get the not authorized error when they try to log into the regular dashboard.
