When it’s my last day of work should I tell my manager (who is the reason why I will be resigning) how I actually felt about her, or should I take the high road and take a graceful exit?

P.S – there is a group chat with everyone that works in our Kendra Scott store and I plan on sending a nice message on there when it’s my last day bc I truly enjoyed working with everyone else. So that’s why I was wondering if I should even tell my manager she’s the reason why I’m quitting.
