Custom button

Hi!
I’m willing to include the social URL of each member in its corresponding profile.
I’ve already set up the profile page with dynamic pages and all profile data is in a collection.

What I’m trying to do, is to add social media icons (Twitter, LinkedIn, and so forth) images and connect them with the dataset so they become fully functional buttons and each profile matches its own data. And, if there is no data available, then hide the button.

Can anyone guide me on how to do this?
I’ve checked tutorials on upload buttons, but couldn’t find any info on how to make this actually work. Makes sense?
