[otrs] how to show "note-external" in drop-down control on close ticket screen

Hey all, Hope you are all healthy, wealthy, wise. I am going to feel really bad here posting this since I just know that this has been asked before, but here goes. How does a sysadmin allow the "note-external" option to be shown on the "close ticket" screen? Ours only allows the agent to leave a "note-internal" as they close a ticket. Great stuff, guys, Thanks so much! Keep up the great work. Keep this list cranking! Namaste, Jason Sjöbeck
