How to generate previews of plotly dash app when the link to dash app is shared on Social platforms?

Hi,
So I built a dash app, and now I want to share it on LinkedIn. When I include the link to the app on the post, there is no preview generated for the app. Also, if the dash app is embedded in an iframe of the website, sharing that website on Linkedin is not generating any previews of the dash plots.

How do I achieve generating a small preview of any plot of the dash app when I’m sharing it on social platforms?
