How to resign in a game

So, first when u play a game in the right,The will be three buttons.

1. takeback . means that if u click that and if your opponent accepts it, It will go to the before move.

2. draw . means that if u click and your opponent accepts it the game will end and nobody wins.

3. resign . means that if u click it then u lose and your opponent win.
