Welcome to the community, @pcjm. Alert notifications are not sent for events saved on the SD card.
The 12-second cloud stored clips and the SD card storage are separate and independent. They are set up and viewed in different areas of the app.
For the SD card storage, go to the camera settings, then Advanced Settings > Local Storage. That is where you set the SD card to record continuously or event-only (1 minute segments).
To view the SD card recordings, don’t tap the Events tab in the app. That is only for the cloud clips. Instead, tap the View Playback button on the live stream view. How you’ll see a timeline under thevideo frame so you can go back in time. You can also remove the card from the camera and view or download the 1-minute video files on a computer.
