How to update current webmap instead of creating a new one during simulation?

Function for Simulink:

function ShowPath(lat_target, lon_target, lat_curr, lon_curr)

% drawnow 
    coder.extrinsic('webmap');
    coder.extrinsic('geoshape');
    coder.extrinsic('fullfile');
    coder.extrinsic('wmmarker');
    coder.extrinsic('wmline');
     
    wm = webmap('World Imagery');
    s = geoshape([lat_target lat_curr],[lon_target lon_curr]);
     
    iconDir = fullfile('C:\Users\andre\OneDrive');
    iconFilename = fullfile(iconDir,'pngwing.com (1).png');
    wmmarker(lat_target,lon_target,'Icon',iconFilename)
     
    iconDir = fullfile('C:\Users\andre\OneDrive');
    iconFilename = fullfile(iconDir,'curr.png');
    wmmarker(lat_curr,lon_curr,'Icon',iconFilename)
    
    wmline(s,'Color', 'blue', 'Width', 1);
end

lat_target and lon_target are unchangeable parameters. lat_curr and lon_curr are changed in the modeling process (the data is taken from the simulink model).

How to update the map during the simulation without opening a new one every time?
