Hollaex website setup

When sharing the link of our exchange (built with hollaex), i’d like it to have a preview logo/little description show up next to the link.
I tried open graph, but it didn’t work. Is there any other way?

Thanks a lot

How did you apply opengraph? You should put it in the index.html in web here: https://github.com/bitholla/hollaex-kit/blob/master/web/public/index.html
