Riot make a log out button

Seriously , 10 years of development and you still didn't come up with a log out button ? Really ? closing the client and opening it back up is a pain in the ass , especially on my low pc , and that shitty @new@ client , and i am 100% sure that riot said this once

"Clients that were able to run the legacy client can run the new one just fine , the reason we cant have two clients its because we cant handle both at once" is not that right ? where is my log out button that when i click it logs me out without exiting so many shit and reopening in a total of 10 mins of opening a client , Come onnnnnnn

Ps. for those people who will ask "why would you log out , do you smurf ?" No i am against smurfing , but we are more than 1 brother that play this game
