Connect iphone to macbook through hdmi using lihhtning to hdmi connector

I Have a iPhone 5s, a macbook pro 2014, and a lightning port to hdmi connector. I was expecting to plug the connector into my iPhone and to hdmi on my MacBook, but nothing happens when I do. I would like the be able to play videos from my iPhone onto my computer. What am I missing? This should be easier, I am quite disappointed honestly. what am I doing wrong?
