Logout action

[Deleted user]

Hey everyone,

There is a action called new conversation so you can make a new conversation.

function newConversation () {
    document.querySelector('button.icon-chat').click();
    document.querySelector('input.input-search').focus();

    var header = document.querySelector('div.drawer-title');
    header.style.left = '0px';
    header.style.bottom = '12px';
}

How can I make a new action to logout from WhatsApp Web?
Here is how I started:

function logout () {
    document.querySelector('button.icon-menu').click();
    document.querySelector('button.Log out').click();

    var header = document.querySelector('div.drawer-title');
    header.style.left = '0px';
    header.style.bottom = '12px';
}

Can somebody help me?
