Hi bro, Do you know remove a shape draw like paint in react leaflet?

[hamish0361]

I write this code for the function to draw the shape like paint:

let paintMode = false;
var myPolyline;

map.on('click', function() {
  paintMode = !paintMode;
  if (paintMode) {
    myPolyline = L.polyline([]).addTo(map);
  }
})

map.on('mousemove', function(e) {
  if (paintMode) {
    myPolyline.addLatLng(e.latlng);
  }
})

And now I wanna write a function this can help me remove this shape. This is a video demo of the function draw shapes like paint: . Thank a lot.
