Let's start by creating a role!
Head on over to 'FBO Settings' and select the submenu 'User'
Then, select 'Roles' on the top left corner of the user page. Once you're on the 'Roles' page click on '+Add Role'
Now it's time to create your role and set up permissions!
1) Name your Role
2) Select Permissions: This is where you can customize the role and select what you want that role to have permission to do in X-1.
For each category be sure to click on the + sign to deploy the sub categories.
