New roles can be added and defined in the Roles submodule of the Users module at the Global level of Azavista, in the left navigation menu. To create a new role, click on the Plus button and fill in the required fields.
You can then define the role (scopes) either in the same popup window, or by leaving the field empty, clicking save, and then going inside the Role's detailed view from the roles list.
Inside the role's detailed view, click on the Role definition tab. There you can start adding or removing permissions for certain parts of the platform, such as CRM or Themes permissions (create, delete, edit, etc.). You can select some or all options for a certain module - fully tailor this to your needs.
Make sure to switch the "Edit mode" button on to be able to edit these permissions. By using the Personas filter and clicking the + button, you can also quickly add a set of permissions that are related and needed to be able to fully perform a specific complex action in Azavista, without the need to search for them individually in the list below.
Don't forget to save your changes when you're done.
