a simple script, only 23 lines of code, not counting comments - 16 lines. Maybe someone will need it.

Permission:
staffchat.view || for the audience
staffchat.use || for those who need to write a message in the admin chat

Command:
/staffchat(/sc) (message/colored msg).

p.s you can do whatever you want with the script, only save my nickname in the script, which is on the first line
