There are two additions that I think would work well for this application.
Add a setting where the user can set how frequently a chat message is sent that alerts to bots on the opposing team. It could be set for every 30 seconds, every minute, or something else. This would be useful for those who want to keep the chat warnings on, but want more control over how frequently a message is sent.
Chat alerts for bots joining the player's team should be added too. Sometimes a bot could slip by and having the alarm sounded as soon as possible for both teams would be very beneficial.
