Is it possible to add a custom message in chat when a player enters the raid bubble?

Hello, I was wondering if I can set a custom message to show up in chat when entering the raid bubble to remind players of rules, or perhaps a chat command? 

you can edit the OnPlayerEntered messages in the language file

"<color=#FF0000>You have entered a raidable PVP base!</color>\nRead the server rules: /rules"

just put the \n so it's on a new line, and then add your message to that.

Thank you so much for the quick reply and all of your top-tier plugins!
