Export users for multisite

Hi,

First, thank you for this plugin. I’ve used it successfully to import users from a standalone site into a multisite.

Now I want to export a CSV file from a multisite, but get an error:

By default, admin and store manager are given access to export users. Please visit here for more details

I’m logged in as super-admin and I read the documentation and added the code below to a must-use functionality plugin, but continue to receive the same message:

add_filter('hf_user_permission_roles', 'add_additional_user_role', 10, 1);
function add_additional_user_role($wf_roles) {    
    array_push($wf_roles, 'super-admin');    
    return $wf_roles;    
}

Is there anything else I should do?

Thank you for looking into this.
