How to show which products have variants on a collection page

Store Design

I am developing a website with the Editions theme.

On a collection page, I want to specify which product has variants by adding a line to product-item that says more options available.

How would I go about doing this?

Use the product object properties to check for more than 1 variant

{%- unless product.has_only_default_variant -%} More Options Available {%- endunless -%}

Or check the variants array size

{%- if product.variants.size > 1 -%} More Options Available {%- endif -%}

Or the options,etc etc
