What can the Google Contacts app do, that requires it to *read* notifications?

Settings > Notifications > Device and app notifications (Control which apps and devices can read notifications) "Contacts" is listed as an app which I could allow to read notifications. It currently happens to be disabled. Why do I see it here? What features does the Contacts app have, that would request or use this permission? --- * Android 14 (Pixel 8a) * com.google.android.contacts * Version 4.37.39.6560300857 * "App installed from Google Play Store"
