What is the best way of resuming game scene after the menu scene?

I want to have 3d menu scene in my game. While in the game scene, when the user clicks menu icon menu scene should load. And when user clicks resume game the game scene should be resumed from its last state. Is there a simple, efficient way to do it or is this out of Unity's standard work logic?

PS: I know that I can write lots of code to save every game objects every attribute, every variable value, every state to an scene state object and make it persistence between the scenes and when I reload the game scene run through the saved state object to set every game object to their last saved states but thats a lot of work and doesn't seem to be the right way...
