WooCommerce to show cross-sells on a product page by showing Featured Image 2

I want WooCommerce to show cross-sell-s on a product page by showing “featured image 2” image of the product. I have already added cross-sells to product page by adding a snipet into functions.php in the child of Porto theme. However, I do not want it shown as product style by default (title, main image, add to cart). I want each cross-sells product to be shown (visualy represented) by featured image 2 of that product (only featured image 2 to be shown, nothing else), and when you click featured image 2 you go to that cross sell. I suppose it needs small change in functions.php
Please help me with this,
