After registering the smart rich menu, the changes will be applied to your LINE official account.
When the default menu is set, the menu is updated immediately, and when the smart rich menu specified by the target list is set, the menu is updated at the timing when a LINE friend sends a message or when the message is sent from you.
The following is an example of usage. Create a contact list with the "Language" property set to "Japanese".
Tap the "Change Language" menu in the default rich menu.
Set "Japanese" in the "Language" property of the contact by using the automatic response function described later. The rich menu changes when the application to the list is reflected.
