Nothing happens

Hi!

I think this plugin is just what I need to make the Woocommerce Bookings and Product Vendors less messy in the back-end for Vendor Admins at my site.
However, as I select user roles (pretty much all of them) and menus (pretty much all of them), I see no difference in the back-end for the Vendor Admin.
Thus, I wanted to reach out and see if anyone has been able to accomplish this, or if someone could let me know if this is not possible using this plugin?

Thanks,
Robin
