I did this, however there is no way to distinguish in the results what the variable product is. All the results are the same, they all have the same picture, product title, and description.
Well, you can set variation images on the WooCommerce variations panel: https://i.imgur.com/lF3MSav.png
That should show up with the variations.
Also, try this configuration for the Primary title field: https://i.imgur.com/5QvA2mR.png
That is sort of a ‘hacky’ way to try to press the plugin to request the title again, and in case of WooCommerce it sometimes helps to get the correct stored variation titles.
