Your widget display can have one of two lightbox options:
Default Lightbox - shows basic information such as the username, avatar, and caption.
For PDPs, the default is the CTA assigned to the content.
Call to Action - add a CTA that links to another page in a new tab in addition to the basic information.
If you choose the Call to Action Lightbox, then it will become your default CTA for the content in your display. If you choose to assign products or update the CTA information on individual pieces of content, this will override the default CTA lightbox.
