change the url in social media card

[duceduc]

Hello. My main site and pano site url are different. The pano images are pull from a sub.domain.com. How can I change the below mark in red arrow to my main site url? I am using the normal.ggt template

[k.ary.n]

I'm not entirely sure how (or if) that can be changed. I've tried adding og:URL and using a different URL from where it's hosted, but that didn't work. But maybe you'll find help in this doc: https://ggnome.com/doc/pano2vr/reference/html-template/
