TIL: Count number of products of current type in Shopify liquid templates

On the product page of a Shopify store I want to insert a link to a page showing all products of this type, but only if there are more than one product of this type.

{% assign number_of_type = collections.all.products | where: "type", product.type | size %}
{% if number_of_type > 1 %}
  {% comment %} Insert comment {% endcomment %}
  {{ product.type | link_to_type }}
{% endif %}
