Check whether lightings of a map are built or not

Hi everyone.

I don’t know how I can checkout whether a map is throughly built in terms of lighting or not. I want to send a project to the unreal marketplace and one of the things that needs to be checked is that the lights of all maps should be built. I sometimes make a small change after my lights are built and I start to wonder if the lights need to be built again or not. And I sometimes even forget which map I built and I need to check that but I don’t know how. Building lights take time and there should be somewhere in the engine to check its status. Where is that?

Thanks for all the help and responses in advance.
