Changing the sound on mobile phone

[Bobette]

Do you know how I can change the 'blob' sound that is sent to my iPhone when people are getting near my battery-operated Nest doorbell? I would like to replace it with some other sound but I don't see how I can do so in Google Home. Any idea, please?
Thank you.

The only thing we can do on the iPhone is to go to our iPhone settings, Settings | Sounds & Haptics, and change the sound used for "Default Alerts", but this affects all apps that use that "Default Alerts" sound.

I’ve been looking though this forum to find an answer for this. Regular notifications (from apps and whatsapp etc) I ignore untill I have time for them, but when someone rings my doorbell I want to hear a different sound, so that I can respond immediately. 
I saw people have been asking this for a while now, would be nice if Google could make this work. Really thinking about getting a ring doorbell instead…

I fully agree.
