Create user roles with different privileges and access using Bubble.io

We are going to show how to create user roles in our Bubble.io application. Our application is small marketplace. So, we need to have users with one of such roles : administrator, seller or buyer. Administrators will have such rights: edit and delete other users such as sellers and buyers. Regarding product management, admin is able to edit, delete, publish own products and products of sellers. Sellers will have access to create, edit, delete and sell their own products. Buyers are able to buy products and see own purchase orders.We want to give the ability to new registered users to select one of the two roles : Seller or Buyer.
