Currently, in MacOS, you can only select an element if you are on the appropriate tool. Meaning you have to change tools to select an element.

IpadOS is better a long press gives you the option to zoom or edit - the zoom option seems a little redundant when it's easy to press the zoom button and drag the box. I feel it would be better if it just defaulted to "edit". Maybe this could be a preference option if there are people who use the zoom box a lot.
