Zooming in - 360 equirectangular

Hello - I’m using 360 images from skybox in my projects. However, in play mode, I seem to only be able to rotate from side to side— Inwould like to be able to zoom in and out. Is this not possible with 360 images? Secondly, when I upload a 3D art gallery model from sketchfab, again I’m unable to zoom into a piece of art hung on the wall. Is this because I’m using an iPad? I have an M4 iPad Pro.
