php - Wordpress WooCommerce Add to Cart Button issue with variations and custom product addons

I will try to explain my issue as best as possible. I have got 3 variations and few product addons on my Product Single page.
The product addons were created with help of this article below:

The Add to Cart button becomes available as soon as I choose all the variations but I need the button to show after you fill in custom product addons.
Is such a thing possible at all?
