How to Move Around A Minesweeper Map?

So I'm using a tutorial from Udemy in order to learn how to make a Minesweeper game. The major problem I'm have is how to deal with tiles that expand past the edge of the screen. I'd like to be able to allow players to move around the screen so they can see all the tiles. The tutorial doesn't cover this. What's the best way to do this? Can someone either help or link me to a tutorial that will help me learn how to do this?

Move the camera via script. You could use the unity's Input features such as Input.GetKeyDown for moving with arrows. You could also detect the placement of the arrows either by tracking the mouseX and mouseY of the mouse.
