Customers also bought section in cart drawer

Question

I'm trying to add "Customers also bought" section under the added items in the cart drawer. I'm doing that by checking for the tags that start with '__with', then getting their handle Now some tag products are duplicates of the ones already in the cart. How to remove duplicates?

I added this logic inside the cart-drawer.liquid.

          <div class="CartAddons">
            <div class="CartAddons__Heading">Customers also bought</div>

            {%- for item in cart.items -%}
                {%- assign tags = item.product.tags | join ' ' -%}
                {%- assign product_handle = tags | split: '__with:' | last -%}
                {%- assign associated_product = all_products[product_handle] -%}

               {%- if tags contains '__with' -%}
                  <div class="CartAddons__Section">
                      <div class="CartAddons__Item"> 
                        {% render 'product-item', product: associated_product, use_horizontal: true, show_labels: false, show_product_info: true, show_vendor: false, show_price_on_hover: true %}
                      </div>
                  </div>

               {%- endif -%}
            {%- endfor -%}
            </div>

Need to develop such logic to check if a product is already in the cart.

{% assign productsInCart = cart.items | map: 'product_id' %}

and then make sure the tagged product is not into the cart items array

{% untill productsInCart contains associated_product.id %}{% endunless %}
