Can anyone help in this regard?
Chances are that you are missing a lot of the support JS libraries that power that feature. You can try copying the HTML, and you can probably make the CSS look fine .... but you'll need to wire up buttons yourself.
One thing you might want to try (and this sounds weird), but at the bottom of your Overview page, add in the Actions Widget (under other). It brings a lot of these shared libraries into the DOM, and it might just help with some of that code. It's not a guarantee, but its worth a try.
Barring that, you can either use the API on the existing piece of content
/contents?filter=entityDescriptor(contentType,contentId) to get the API content object, where you can use the resources attribute to find the end-points to Like and Follow (but the UI wont be as clean as the native)
Hope that helps.
