What is correct pattern to create item with several options

I'm developing a web app using angular and material design. At this moment, when I'm creating a new role I enter name and description of the role and role is created. After discussion with colleagues, we decided that we cannot create a role without adding at least one permission. What is the correct pattern to add permission in role-creation form?

Current role creation form:

Role permission's form:

Any ideas how I can integrate role creation form with role permission form?
