You should have a button available to the right side of your player profile banner (top right of the screen), like this:

Although I did notice it occasionally doesn't show up when using mouse and keyboard, it'll be fixed in the next patch!
As a workaround, you can access the same menu from the Player Profile button in the main menu.
