Get User Input from webmap

Dear all,
is there any way to get the coordinates from the cursor (which are already displayed at the top right corner of the browser window) on a webmap when i click on the map.
I want to add manually lines from user input to the map and store the points in workspace to do further processing. The problem is, that only webmap provides panning, zooming and high-quality maps. I already tried to get the osm data from WMS and vizualize them on my own, but to provide (wordwide) zooming and panning i need to download the whole OSM-data (approx. 80 GB).
The best solution would be a onClickListener, which grabs the geographic coordinates (from the browser window). Then i could save the data and draw the lines with wmline. On the Matlab documentary they show a similar example, but they read the coordinates manually. (https://de.mathworks.com/help/map/annotate-the-web-map-with-measurement-information.html).
Thanks in advance.

inputm can be used to get the lat-lon data on mouse-clicks from a map. I am not sure if this can be used with webmap’. Try using inputm’. For more information refer to the following link

Thank you for your answer.
'inputm' doesn't work, beacause webmap creates a canvas. There are no axes objects which are needed for 'inputm'.
Maybe this functionality should be included in one of the next updates. The coordinates of the curser are already displayed in the canvas.
