Hello,
There are a few ways you could approach this depending on where you want the notification to appear.
For example, Power Automate can trigger when a new record is created and notify the relevant users through email or Teams. If you want the notification to stay within Dynamics 365, you can also look at in-app notification options rather than relying on the Insights card.
If you're looking for something that can trigger an alert directly from a record creation event, Alerts4Dynamics is another option to consider. It supports Event-Based Alerts, so you can configure an alert when a new record is created and choose how it should be delivered, such as a pop-up, form notification, or email. You can also target specific users or teams.
So, for a new web submission, the setup could essentially be:
New submission/record created → trigger the alert → notify the appropriate user/team.
The best approach would depend on whether you want the notification in Dynamics 365 itself, Teams/email, or a combination of these.
