I'm trying to send the same proactive message to many users within my organization. We are working with a Microsoft Teams bot, built with JavaScript.
We're currently looping through the users, grabbing their conversation reference, then proactively messaging each user 1 at a time.
We are sending the same proactive message to these users, so I'm looking for a way to send this message to a list of users with 1 call
We're currently using the 'continueConversation' function to proactively message users
To my knowledge, getting a conversation reference for everyone who has previously messaged your bot and looping through while sending a message to each is the currently accepted method of implementing proactive messaging to all users.
For reference, the docs on proactive notifications and the javascript proactive bot sample.
