1st of all zoomPlot() is a 3rd party function and is not part of MATLAB 2022b package or its toolboxes. Therefore, to see what can be done with it and how to use, it is worth viewing the content of this function. That can be achieved by:
edit zoomPlot % from command window
%% OR
open('zoomPlot.m') % from an M-file or MLX-file editor
edit 'zoomPlot.m' % from an M-file or MLX-file editor
If you want to use zoom option programmatically, there is a MATLAB fucntion to get it - zoom. See this DOC.
