Remove a tile from a scene with GDScript

Question

How do I remove a tile from a scene programmatically? I have tried the following to no avail:

_physics_process(_delta):

    ...

    velocity = move_and_slide(velocity, Vector2.UP)

    for i in get_slide_count():
        var collision = get_slide_collision(i)
        if collision.collider.name == "MysteryBox":
            remove_tile(collision.position)

func remove_tile(position):
    var tilemap= get_parent().get_node("Tilesets/MysteryBox")
    tilemap.set_cell(position.x, position.y, -1)

I can detect the MysteryBox when the player collides with it, but the remove function is not removing the tile the player touched from the scene. Thanks in advance!

Changed func remove_tile() to pass the collision object and modified the function as follows:

func remove_tile(collision):
    var tilemap = get_parent().get_node("Tilesets/MysteryBox")
    var local_position = tilemap.to_local(collision.position)
    var cell_position = tilemap.world_to_map(local_position)
    cell_position -= collision.normal
    tilemap.set_cell(cell_position.x, cell_position.y, -1)

Now the collision works and the tile is removed form the scene...
