On the Admin panel, go to the Role Management section, and then click on Roles & Permissions tab.
Once there, you'll see the button to create a Custom Role.
The key elements that we must take into account to create the role are the followings:
Assign role name
Scope Description
Check those sections that will be accessed in the future by anyone who is assigned this new role.
Once the 3 items are completed, click on Save.
This way we are creating a custom role that can be modified, deleted, and assigned to anyone in the organization.
