Adding MENU text beside the hambuger icon

Site URL: https://www.todoinc.co/

Hi everyone, 

Just wanted to ask how I should go about adding the word "MENU" right beside the hamburger icon in the navigation.

I'm using the Ready template in the Skye template family. Ideally, it would look something like this:

What code can I inject here? The site is https://www.todoinc.co/

Add to Home > Design > Custom CSS

.nav-toggle-label:before {
    visibility: visible;
    content: "HERE IS MENU";
    color: #000;
    font-size: 20px;
    background: #f1f2f8;
    padding: 10px 20px;
    border-radius: 20px;
}

It works perfectly!! Thank you so much, @tuanphan !!!
