Starting a game with a custom URI?

I would like to be able to launch a game lobby from a link on a webpage. The goal here is to have a list of servers on a webpage, and clicking on them would launch the game and put the player in the lobby.

Is there a way to register a custom URI with a UE4 game? For example, a URI that looks like this:

mygame://127.0.0.1:1337?user=johndoe&pass=hunter22

Pasting that into an address bar should launch the game, connect to server 127.0.0.1:1337 with the username “johndoe” and password “hunter22”.
