Any way to tell iCloud or iOS to only sound a notification on phone rather than some other nearby device?

Ok so maybe I posted this in the wrong forum and misunderstand what umbrella the services fall under or what exactly is happening.

Apps make notifications in iOS. Apple also makes notifications like when you go to log in to your Apple ID on a new device, or when you get a message in iMessage, or voicemail or phone call, etc.

What seems to happen is that whether from apps or from Apple (not sure if it is just some or all of these but like if you get a phone call I think it only audibly rings on one device, or get a text or voicemail), if notifications make a sound, it will only be on one device even if you have many logged in to the same Apple ID. I'm not sure whether this is by locality (like if they are all in the same room or same basic location) or if it would happen even if the device-other-than-my-phone were not nearby. I want all these notifications to make a sound on my phone instead of randomly (?) pick another device.

Maybe this is two or more separate issues. Maybe it's the Apps themselves doing it each individually. I want my phone to always make a sound when there is some notification on the pool of devices logged in to the same account(s).

Thanks.

Also I think I was confused this morning because my bluetooth headphones had been left on and I was hearing sounds from elsewhere. Maybe it is just apps that are doing it and not actual Apple/iOS notifications.

I think I conflated how Siri only answers on one device (or seems to) if there are multiple ones in the room with how certain apps seem to only make one audio notification and not necessarily on the device I want it on. The actual Apple notifications do happen across all devices.

Generally, a third party app will only notify you on a specific device.

Yeah that seems to be the problem I am having. I assumed this was a feature of iOS and some kind of service but I guess that was a bad assumption.

Did you see my subsequent comments/replies? I explained some of the confusion.

Yes.

Why don't you take a guess and I'll tell you if you're right. You managed to guess correctly what you think the right term for "iCloud Device" is so I have high hopes.

Yes the app(s) are installed on the other device(s). I thought maybe this was a feature of iOS to direct the notification to one place rather than ding on all of them.
