Customers can now join Amazon Chime meetings on Echo Show 8. We recommend customers simply link their calendar using the Alexa app. Once linked, customers can say, “Alexa, join the Amazon Chime meeting” or “Alexa, join the meeting” at the time of the meeting to enjoy the meeting experience on their Echo Show 8. If customers do not wish to link their calendars, they can also speak the Amazon Chime meeting ID at the time of the meeting to join the meeting.
