Imagemap message
Imagemap messages are messages configured with an image that has multiple tappable areas. You can assign one tappable area for the entire image or different tappable areas on divided areas of the image.
組圖訊息能夠給予許多地方做按鈕但是無法明確表示所以需要用圖分開才比較明顯
You can also play a video on the image and display a label with a hyperlink after the video is finished.
甚至我們可以在其中放入影片(仍然不推薦因為跑得真的很久)
