How do I make microphone work in iOS app.

I'm trying to make Construct 3 advanced example "Microphone input" work as iOS app (because when this example will work, also my app will work).

This is the error I get in the Xcode:

WARN: Error requesting microphone: TypeError: undefined is not an object (evaluating 'navigator["mediaDevices"]["getUserMedia"]')

p.s. all is working fine when opened as a remote preview in the safari browser
