Shopify Liquid and Ajax: Adding and Removing Products in Cart Based on Conditions

I'm working on a Shopify store and trying to implement a feature using Liquid and Ajax. I have a script that adds a free product to the cart when a qualifying product is present. Additionally, I want to remove the free product if the qualifying product is removed from the cart. Here's the existing code I'm using: <script> window.onload = function(){ let cartContainsFreeProduct = false; let cartContainsQualifyingProduct = false; const qualifyingProductVariantId = ***ENTER VARIANT ID OF PRODUCT THAT QUALIFIES FOR FREE PRODUCT***; const freeProductVariantId = ***ENTER VARIANT ID OF THE FREE PRODUCT***; {% for item in cart.items %} if({{ }} === freeProductVariantId){ cartContainsFreeProduct = true; } if({{ }} === qualifyingProductVariantId){ cartContainsQualifyingProduct = true; } {% endfor %} // If cart contains qualifying product and doesn't already contain free product, add qty 1 of free product if(cartContainsQualifyingProduct && cartContainsFreeProduct === false) {'/cart/add.json', { quantity: 1, id: freeProductVariantId }) .done(function() {window.location.reload()}) } } </script> The script for adding the free product seems to be working fine but how do remove the product freeProductVariantId when removing the qualifyingProductVariantId from the cart
