Using mouse button to get lat long coordinates

I am using App Designer to display maps. When a check box is selected, the map will be displayed. This works fine. However, I would like to click on the figure and get the latitude and longitude of that point. I tried to use inputm but I get the following errors

Error using gcm>checkaxes

Input is not an axes handle.

Error in gcm (line 24)

h = checkaxes(varargin{:});

Error in inputm (line 45)

gcm(hndl);

Not sure what the errors mean. How to get the lat long with a mouse click ? What am I not doing correctly ?

% Value changed function: StreetViewCheckBox

function StreetViewCheckBoxValueChanged(app, event)

app.street_view_selected = app.StreetViewCheckBox.Value;

if app.street_view_selected == 1

app.fig_street = figure('Name', 'Street View');

app.fig_street.Position = [1350 700 1200 800];

app.street_view_handle = geoaxes("Basemap","street","ZoomLevel",12);

hold('on');

geoplot(app.street_view_handle, app.obslat, app.obslon);

[lat, long] = inputm(1);

else

close(app.fig_street);

end

end

I have different maps under tree and when maps are checked map should display and has to be off when turned off. so next I want to use mouse click event to get the lat and longitude value. Tried it for a day and didnt work

the inputm function does not work with geoaxes. Try using ginput instead.

[lat, long] = ginput(1);
