How do I delete an LTI Advantage tool?

Options

I can see a list of LTI Advantage tools on the page at d2l/le/ltiadvantage/registrations/home but I cannot see an option to delete an item from the list, merely to enable/disable it. Is there a special role/permission needed for deletion? I have tried ones like "Delete External Learning Tool Links" but none seems to have had any effect.

 

Thanks.
