Facebook share, custom url on app name

Hi I am using cordova-plugin-facebook4 to post image from my app to user’s facebook wall.

How do I add a custom url to my app like intagram does, so user clicking on my app name would go directly to app’s web page post? See image below

This seems like something that would be on the docs on Facebooks dev site…

Well the proglem that there isn’t. I can add url like myweb.com, but there is no info how to do like this
myweb.com/post/5454545. Ionic native facebook plugin also doesn’t provide any info.
