Nuclues + luckperms problem

Hi, I need help with configurations Nucleus tam coś tam. I wanted to make player’s chat Look like that :

&a&lPLAYERNick &a&l> &r

And admin’s chat like that :

&6&lADMIN Nick &6&l> &r

But i can’t do it by myself, i was trying to do something with config and permissions but i can’t get the effect. Can someone please help me?
Documentation Nucleus didn’t help me… :<

Thank you in advance
