[Mailman-Users] Removing the option to delete a list on the Postorious interface

Hi, I have a question on the Postorious web interface in Mailman 3. I have found that a list owner can delete a list through the Postorious interface if they have the role of owner to the list. I wanted to have it either disabled or removed but I am not sure where to look to make changes to it. I would rather remove it from the interface totally so it would be done from the command line. Any help would be greatly appreciated.
