IOS access to microphone

Our website allows users to record an playback their own voice.
Safari on IOS will generally ask the user for permission to use the microphone for every webpage that attempts to access the microphone, unless you change the website settings from the address bar and grant access to the microphone for the entire domain.
In the Gonative app this setting is not accessible because there is no address bar. Is there another way to grant access - or let the user grant access to the microphone for the entire domain the app is built for?
