The extension can send you notifications about different topics, for example a new SEGGER J-Link version.
The following image shows an example of the notification you can receive.
If you miss a notification, click the notifications ring icon to open the notifications menu with the list of most recent notifications from both Visual Studio Code and the extension. There, you can also configure the way you want to receive notifications.
Tip
Some notifications have a Don't Show Again button. Clicking this button will stop the notification from appearing in the future. If you have hidden a notification, but wish to see it again, run the nRF Connect: Reset Notifications command from the Command Palette.
