How do i set my camera size?

working on a project, the normal camera scrolls to the player. But for the boss fight i want it to cover the entire layout not just a certain area ive been playing around with stuff and nothing seems to be working open to suggestions

thanks

I tried setting the camera to another object in the middle of the map and changing the size of that.i also tried adjusting vanishing point and projection. and other along the lines of that. im pretty new to construct so i havent learned a ton but for the most part have been able to work my way through my game. just getting stuck with this part

Oh my gosh nevermind i found the viewport adjuster

Thanks you for answearing though :)
