did you hit reload after you made your changes?

BTW for those wanting to accomplish the same. Here is how I did it without making any changes to server-side code.

Add the contents of the below file to the custom scripts under 'Setup > Custom Script' and edit the ‘default_msg’ variable.

Also, a question to the experienced devs here. will this be considered a 'workaround/hack' or 'an accepted solution'?
