Battle net vs. launchpad

Hey guyz, just wanted to ask about launchpad.

I am playing heroes of the storm, so now i have two icons in launch pad: battle net app, and installed game heroes of the storm.

Battle net is same game provider like Steam, but however i don't see all my steam games in launchpad like i do about battle net application.

I am opening the games just thru the game privideing apps, not by icons.

So i would like to know, how can i hide or erase the heroes of the storm icon from launch pad.

Thank Yall.
