How to use the pixi.js.Point function in pixi

canvasCoordsFromStageCoords(stageCoords: Vector): Vector {
        if (!this.entitySystemDisplayObject) {
            return stageCoords;
        }

        return this.entitySystemDisplayObject.toGlobal(
            new Point(stageCoords.x, stageCoords.y)
        );
    }

private renderChunkMapMode(chunkX: number, chunkY: number) {
    const mapMode = this.mapModes[this.viewOptions.mapMode];
    const chunkCells = this.getCellsInChunk(chunkX, chunkY);
    const { cellWidth, cellHeight, chunkWidth, chunkHeight } = this.options;
    const chunkPosition = new Point(
      chunkX * chunkWidth * cellWidth,
      chunkY * chunkHeight * cellHeight,
    );
    mapMode.updateChunk(
      chunkX, chunkY,
      chunkCells,
      chunkPosition,
