WooCommerce and FastSpring blocks help?

I’m using FastSpring (popup Store) to manage the eCommerce side of payments. But, I’d like to use WooCommerce for how well they display products/catalogs.

I found a good resource on how to use WooCommerce without the Buy/Add To Cart feature: https://www.wpbeginner.com/plugins/how-to-create-a-product-catalog-in-wordpress-without-a-shopping-cart/ … however, what I need to accomplish is to use FastSpring blocks (from the FastSpring plugIn) for my “Add to Cart” and “Buy” buttons rather than the WooCommerce buttons.

Is this possible?

Cheers, Rob.
