Costumization of the Redball color in the discord notification in the PC hotbar

Basically consists on changing the color of the Redball in discord notification that appears on the PC Hotbar. The costumization of the Redball would work like this example. In server X i choose that whenever a message is sent to the chat purple. I Would get a purple ball on the discord notification located in the PC hotbar. The costumization of each server would only apply if the server is open when you minimize discord. This way, i can know in which chat a new message has appeared and if it is important to me or not.
