Fix ‘Add Role’ Option not there in wordpress 5.2.2

“Add Role” isn’t an option in WordPress, and never has been. If you want to add a role you’ll need a plugin like User Role Editor or Members.

If you want to add a role with code, you can do this with the add_role() function:

add_role(
    'member', 
    'Member', 
    [
        'edit_posts' => true,
    ]
);

Just be aware that roles are persistent, so this function should only be run once on theme/plugin activation.
