How do I change my menu header item letter spacing only?

[kirstenlc5]

Hello, I found how to change my letter spacing in my menu items to 0.09rem, but now I have no idea where to put the code on my Shopify store. I am using the dawn theme.

Here is my store: try-nellies-boutique.myshopify.com

Thank you so much, I will make sure that I pick an accepted solution for you!

Hello,

.header__menu-item {
	letter-spacing: 0;
}

Add this css at the bottom of Online Store->Theme->Edit code->Assets->base.scss.liquid
