Zoom In-Out and pan move in a specific window

Godot Version

4.4

Question

Im trying to replicate a fake OS in godot and I’m block at the Zoom in and out as well as pan movement in a specific window (for example a fake website).
My window itself is panel and I’m trying to get a camera that I’m to move as well as do zoom in zoom out. The object itself is not fitting the windows and should not be seen outside of it (which is the case right now). I tried to work with Camera2D without success. I also tried to think different, instead of moving the camera inside the windows, move the object. Zoom in and Zoom are then scale up and scale down but I just ended with something funky.
Can you help

Best,
