How do I link post and forum tags?

Is there a way to link post and topic tags and show post and topics associated with the tag on a single page in front end?

I tried doing it using [bbp-single-tag id=$tag_id] short code on post tag page but I couldnt fetch the topic tag id in runtime. Is there a shortcode like [bbp-single-tag slud=$slug], I can fetch the slug from the post tag URL in runtime.
