/**
 *   KEY_PHONE_NUMBER - Recipient’s phone number. If this and the recipients name are not
 *   provided by the application, assistant must do contact disambiguation but is not required
 *   to add the name to the PendingIntent.
 *
 *   KEY_RECIPIENT_NAME - Recipient’s name. If this and the recipient phone number are not
 *   provided by the application, assistant must do contact disambiguation but is not required
 *   to add the name to the PendingIntent.
 *
 *   KEY_RECIPIENT_UID - Recipient’s UID in the ContactProvider database. Optionally provided
 *   by the application. Not required to be sent back by the assistant.
 *
 *   KEY_DEVICE_NAME - Friendly name of the device in which to send the message from. If not
 *   provided by the application, assistant must do device disambiguation but is not required
 *   to add it to PendingIntent. In V1 this is required to be sent by the application.
 *
 *   KEY_DEVICE_ADDRESS - Bluetooth device address of the device in which to send the message
 *   from. If not provided by the application, assistant must do device disambiguation and add
 *   this to the PendingIntent. In V1 this is required to be sent by the application.
 *
 *   KEY_SEND_PENDING_INTENT - @NotNull Will always be provided by the application. The
 *   application must preload the pending intent with any KEYs it provides the assistant that
 *   is also needed to send the message. (I.e if the application passes in the
 *   KEY_PHONE_NUMBER in the Bundle, the assistant can assume the application has already put
 *   this in the PendingIntent and may not re-add it to the PendingIntent).
