(Android/Samsung) Abillity to customly set what color the flashing LED will light up.

So i want to have a custom notification system on my phone.

I have set it so that whatsapp will light up my LED indicator green if there is a unread whatsapp notification present. I wish Discord had this too. I would set my LED color for discord purple so i can differentiate between whatsapp and discord notifications if i have them while my screen is closed.
