The plugin works without a problem. I have explained to the client and I am posting the direct link to the explanation here as well:

The client is not happy with how the Facebook share window content is displayed and wants my plugin to be able to change it somehow.

But I have explained to him that Facebook generates the content of the share window based on the link supplied, there is nothing that I can do to change any content.

The sidebar simply supplies the page URL and the Facebook share tool generates the popup window content.

You can go to the Facebook Sharing Debugger page: https://developers.facebook.com/tools/debug/sharing

Input your own custom URL and, among other data, see the "Link Preview" section which shows a preview of the link box.

Again, I cannot control the text in the share window, that is something that Facebook generates based on the supplied link.
