Add youtube video to fotorama_nav

I know that you can add a Youtube video with the help with Youtube API v3. But I want to know if I can do this programmatically whitout Youtube API v3. Right now we have at product, in admin, a custom attribute called Youtube link and I want to know if I can use that to add an youtube video in an iframe in fotorama_nav. Thank you! It’s Magento 2.3
