Is there any way to just see part of the canvas sometimes?

I’m working on a game where the canvas takes up the whole screen, but sometimes I’d like to focus on one specific part of the canvas. I can’t figure out any way to do that. If I add another camera, make that camera smaller than the main camera (so it would be zoomed in on part of the canvas), then change the canvas to render through that camera, the size of the canvas just changes to fill up the whole screen in that camera. Is it even possible to do something like this? I’ve tried all kinds of search terms about using multiple cameras in one canvas, but I can’t find anything.

try worldspace mode of canvas, than it will not change canvas size depend on camera

are you trying to remove things from the canvas or zoom in on parts of the canvas?

worldspace canvas will do the job .
