I’m trying to add custom data attribute to select options for variations in variable product – to use the taxonomy description I have inside the admin panel.

I’d love to get them to custom attr as I they would be accessable thru JS.

<option ... data-variaton-description="Lorem ipsum (...")>

I found that the function responsible for this is wc_dropdown_variation_attribute_options() but I can’t seem to get it working in my functions.php file.
