Create a responsive burger menu - html

Question

I've made a lot of progress on my site, but the problem is that my burger menu doesn't show up, does anyone have an idea what's causing this please?
I tried different things, debugging and so on but I can't make it appear again -_-
So if anyone knows why, and has explanations I'm a taker I'm completely lost I know what to do lol
And then if you have other constructive criticism on my code of course I'm a taker thank you in advance for giving me your time
$('.m-nav-toggle').click(function(e) {
e.preventDefault();
$('.m-right').toggleClass('is-open');
$('m-nav-toggle').toggleClass('is-open');
})

The "m-toggle-icon" class needs "width:100%" and it will be shown. This is because its parent has "display: flex".
Working example:
$('.m-nav-toggle').click(function(e) {
e.preventDefault();
$('.m-right').toggleClass('is-open');
$('m-nav-toggle').toggleClass('is-open');
})
#import url('https://fonts.googleapis.com/css2?family=Lato:ital,wght#0,100;0,300;0,400;0,900;1,700&display=swap');
#import url('https://fonts.googleapis.com/css2?family=Roboto:wght#900&display=swap');
