Hi EllieMae63,
Thank you for using the Apple Support Communities! We would like to clarify. Are you referring to Do Not Disturb? If so, you can add people by following the steps below:
Use Do Not Disturb with Focus on your iPhone or iPad
1. Go to Settings > Focus.
2. Tap Do Not Disturb.
3. You can select allowed or silenced notifications from people and apps, connect your Lock Screen or Home Screen, have this Focus turn on automatically, and add Focus filters.
If you mean something different please let us know. For example, there is alerting your emergency contacts when using Emergency SOS on your iPhone:
Use Emergency SOS on your iPhone
Hope this helps!
Have a great day.
