Remove Menu from Woocommerce shop

I don’t want my shop to have a menu bar at the top and would like to remove it by adding some code into custom CSS.

I’ve tried a variety of codes and so far nothing is working. Here are several things I have tried that don’t work:

.woocommerce.archive nav.main_menu {
display: none!important;
}

.woocommerce nav.main_menu {
display: none!important;
}

Any ideas? Here’s my shop: https://muttbuts.com/shop/
