Changing Playlist Chat Username

Hello everyone. David here, the Station Manager for the WPRK 91.5 fm “The Best in Basement Radio”. First time posting in the forums looking for some help with the playlist chat.

Recently, one of our DJs figured out how to change the username of the show host in the playlist chat. The DJ changed it to their first name but cannot remember how they did it. Now our other DJs are frustrated because the name that appears when sending messages to chat is not one that represents the whole station.

Does anyone know how to change the username for the host in the playlist chat? Ideally, the station would like it to be “Show Host” or “WPRK”. Has anyone encountered a similar issue? Thanks!
