emission shader

Hi,
When i use the Unity Standard Shader i can modify the Emission value after lightmapping the scene and it affects the environment in realtime. I tried assigning a value to emission but that just affects the material itself, not it's environment.
How can i reproduce this behaviour of the unity standard shader using amplify shader editor?
Thanks
