Wechat meta tagging

[jschee]

This is not an issue, more so of a suggestion or help if there's an already available solution.

So as far as I know the flow of wechat sharing goes like:
scan qr code from wechat -> open webpage to wechat browser -> select option to share on moments

Is there a way to customize the meta taggings so that when shared to moments, the gem can grab a photo from the content and use it as a photo placeholder/preview, instead of the chain/url placeholder?
