+Microsoft Teams administrator can configure policies for data loss prevention (DLP) to prevent leakage of sensitive information from Teams users during Teams meetings. Developers have the option to integrate chat functionality in Teams meetings with Azure Communication Services. This can be done either through the Azure Communication Services UI library or through a custom integration. This article describes how to incorporate data loss prevention without a UI library.
 
-You need to subscribe to real-time notifications and listen for message updates. If a chat message from a Teams user contains sensitive content, the message content is updated to blank. The Azure Communication Services user interface has to be updated to indicate that the message cannot be displayed, for example, "Message was blocked as it contains sensitive information.". There could be a delay of a couple of seconds before a policy violation is detected and the message content is updated. You can find an example of such code below.
+You need to set up your application to listen for real-time updates on message edits. If a Teams user sends a message containing sensitive content, the message will be automatically replaced with a blank message and flagged with a "policyViolation" result. Your application should update its user interface to reflect that the message has been blocked. For example, display a message such as "Message was blocked as it contains sensitive information." Be aware that there may be a brief delay, usually a couple of seconds, between when a message is sent and when a policy violation is detected and applied. You can find an example of such code below.
 
-Data Loss Prevention policies only apply to messages sent by Teams users and aren't meant to protect Azure Communications users from sending out sensitive information.
+It's important to note that DLP policies apply only to messages sent by Teams users and do not prevent Azure Communications users from sending out sensitive information.
