In addition to a notification in the Messages panel, if sound and toast notifications for messages are enabled in your notification settings, a pop-up will appear in the top right corner of the home screen to alert you that you’ve been invited to join a conversation.
Clicking the pop-up will highlight the invitation in the Messages panel, where you then can accept the invitation to join the conversation or to reject the invitation and remove the conversation from the panel.
 | Rejecting a conversation does not prevent officers or dispatchers from sending additional invitations to the same conversation. |
