get zoom status of a UIAxes

For a figure axes, I can find out whether zoom is active or not by doing:

figure
plot(1:10)
h = zoom(gca);
get(h,'Enable') %off
zoom(gca,'on') %start zoom mode
get(h,'Enable') %on

but the equivalent with a UIAxes doesn't seem to work:

>> h = zoom(app.UIAxes)
Error using matlab.ui.control.UIAxes/zoom
Too many output arguments.

How can I find out whether zoom is active on my UIAxes?
