Reply To: Additional content/html to single product vatiations group

Hi, thanks for answer but it doesnt resolve my needs.
I know lay builder, but i need additional text/html to variants (my products have few variants https://prnt.sc/twYOE_Bahon8) – so I cannot add additional text/html to each variant by lay builder, I have to modify template which is responsible for vatiations / swatches.
Could you recommend the proper way to do it? Which file we need to edit / add to child theme?
