Saving a scene with a button and loading it with another button from another scene

Hey so im making a game with levels and I would like help with saving a scene with a button and being able to go back to that same scene in my main menu by pressing a button.

An example is i would be in level 2. I press a button which would save it. I have another button which takes me back to the main menu scene. I have a load button there and I want that load button to take me back to the scene my player was in which was level two. I know would like some simple scripts that would help me achieve this

I know there are other posts like this but I would really appreciate directed help.

Thanks
