FOSUserBundle, the relationship between the user (roles) and the group (roles)?

Question

I am a bit confused with the roles in the FOSUserBundle. The user object also has a role column through which we can assign several roles to the user. According to the answer posted in User Management / Roles / Groups in FOSUserBundle , we do not need separate entities or tables to manage user roles.

I also implemented the FOSUserBundle group, which also contains a set of roles, and the user can be assigned these roles. So, I already realized that we can create a group to assign a set of roles so that similar groups can be accessed using the group.

Now that I’m stuck with the goal of using groups, if the set of roles can only be controlled from the User Entity, or how can I combine roles from the User object and the Group object or something that I’m missing here?
