How to add Minecraft as a Non-Steam game?

I know how to add Non-Steam games; I have already done it with other titles. My problem is that I can only figure out how to add the Minecraft Launcher rather than the actual game itself. Any suggestions?

I don't think that you can, since you need the launcher to log into the game to prove that you have a valid, purchased account.
