Change default handler for tel URL scheme on macOS

My app is a VoIP softphone for Mac that allows people to make phone calls to a regular phone numbers. The app exists since before Mac App Store. The app declares itself to the system as capable of handling tel: URLs. Until now, people could change the default handler for tel URLs in FaceTime settings (Default for calls).

In macOS Tahoe 26, this doesn't seem to be possible any more. That option is gone from the FaceTime settings.

Is it completely gone or has it been moved somewhere else? If there is no UI control for this any more, is it possible to change it programmatically?

I am also looking around and cannot find a way to change those handlers, even a terminal command would suffice. I am trying to change it to another the Teams app.

macOS 26 has a new Phone app. Did the setting land there? [1]

No, the setting is not in the Phone app settings on macOS 26. Although it is on iOS 26.
