Add icon to grandchild element with javascript?

Store Design
1

Hello, someone expert with javascript knows if it is possible to target a grandchild element in order to add an icon?

I would like to add an icon next to grandchild element in navigation menu (DAWN THEME)

I tried to add something like this in header.liquid and in theme-editor.js:

$(document).ready(function () {
$('#shopify-section-header > div > header > nav > ul > li:nth-child(5)').html('');
});

but it doesn’t work.

Any help?

I solved it using the .append function with javascript
