Shortcode with href link

How can I use a shortcode with an href link so that it links to a specific page for each user?

I’ve set up a custom meta entitled user_page and my shortcode is thus [authorinfo field=”user_page”]. I want users to be able to click this link on their account page and be taken to an individual product page on my site using the url I’ve added to their profile. However, I’m struggling to link it up and make it clickable.

Any advice would be much appreciated.
