Extract position of all draw points

Based on this question (https://www.mathworks.com/matlabcentral/answers/545177-draw-points-on-uiaxes-until-you-press-a-button-in-app-designer?s_tid=srchtitle), how can I get all the position of the pointhandles?

function StartButtonPushed(app, event)
            imshow('peppers.png','Parent',app.ImageAxes); 
            userStopped = false; 
            pointhandles = gobjects(); 
            while ~userStopped
                a = drawpoint(app.ImageAxes); 
                if ~isvalid(a) || isempty(a.Position)
                    % End the loop
                    userStopped = true;
                else
                    % store point object handle
                    pointhandles(end+1) = a; 
                end
            end
            disp(pointhandles)
        end

1. Add this to the end after the while-loop to get rid of the initial empty handle

pointhandles(1) = [];

2. Extract the position data from the pointhandles vector.

positions = cell2mat(get(pointhandles, 'position'))

positions will be an n*2 matrix of [x,y] coordinates for n points.
