HomeKit facial recognition/people notifications

I purchased a Logitech Circle View with facial recognition. I receive all the alerts on my iPhone X indicating a motion has been recognized, but how do I have it alert me one of my recognized faces has been spotted on that camera?

I have random sources I could even have my HomePod alert this notification.

I was thinking I could have this camera near my garage and receive alerts remote (or local if the toggle was set as such) indicating “Roberta has been detected on Logitech garage Cam “. However, the only way I can discover if the motion was even a person (and if a person, which name), is by going into the home app.

I see my family members names (and associates pics) in the home app. Which as a side note, if a facial recognition doesn’t seem to correlate to your family member, I don’t find a way to assign the picture to an existing name; I seem to only be sble to add a new name/profile. Is there a way to merge the pics into an existing name/profile?

so 1) how do I get people alerts/notifications? 2) how to merge facial recognition pics with existing names?
