Change custom field front-end output

Hi,

I created several custom fields. One of them is a Link Type field on the Product.

I'd like to change the front-end output format of this custom link field on the Category view and the Product view so that the label is not shown, and the link is shown as a button.

Where can I change the custom field output?

Best regards,
Chantal

After changing the Link Type field to a Text Field with RegEx checks, I was able to create the custom output just for this field in show_block_custom_main of the product. I guess I'll be able to find it for the category view now as well .
