How can i interact with tilemap in the game

Question

Hello everyone, I'm creating a 2D strategy, but I don't know how I can interact with the tilemap in the game, for example, so that when I click on a certain tile, it changes

Here is an example. I haven't tested the code so there might be issues. Also it's not pretty. :D

if event is InputEventMouseButton:
    if event.pressed:
        var pos = event.position
        var x = int(pos.x / 20)
        var y = int(pos.y / 20)
        var clicked_tile_pos = Vector2(x, y)
        # gets the tile index from the tileset in the given position
        var current_tile = map.get_cellv(clicked_tile_pos)
        # sets the tile to index in the given position
        map.set_cellv(clicked_tile_pos , new_tile)

Hopefully this helps.
