Ios and mac license signing

Hello everyone,
I am stuck on something. I am packaging my game for Mac and not ios but I need your help. I have an apple developer license. We have a game launcher that will launch the game on windows and mac and we have signed the launcher. I cannot find where to sign the game for Mac in the unreal engine, I only see for ios. Do you know where to sign the game in the unreal engine for Mac? Any help would be great as this has been over two weeks trying to figure this out on my own. Thank you.
