@vivienrk - you’re welcome. You do have the Perspective camera. In the first image above, there is a hand below the green save dots, left of the terrain with the green frame. You have a directors stool there. Just click on it to change the camera.
Imagine a room where you put your objects in. You standing at a place (near the door, for example) and look at it. When you move around in the room (the camera is your eye), the perspective changes and you see how the objects are distributed in this room.
Again in the first image, there is a grey down-arrow where I put a red left arrow. Above is another such grey down arrow. If you click on it, a menu pops up that lets you look from top, bottom, left, right, front and back on your scene without moving the camera.
