Accessing gameObject from another scene?

Hello, so I have a problem. I have 2 different scenes, one is the main menu scene and the other is the game scene. The menu scene has a second canvas that opens the Campaign menu, and I'm trying to make it so that when I press "Back to menu" button at the end of the game scene it leads me to the campaign menu.The issue is, no matter what I do, when I press the button it leads me to the main menu. I've tried static variables and donotdestroy in order to make a script that opens the Campaign menu instead of the main menu, but it doesn't work, Any help would be appreciated.
