We have developed a Bluetooth external Braille display and want to have it added to to the list of Braille displays supported by VoiceOver: https://support.apple.com/en-gb/103246 How should we proceed? Thank you.

I am using objective-c to develop a custom keyboard on iPhone X to run in landscape orientation. I want my to make use of the full iPhone X screen and have my custom keyboard layout extending from left edge to right edge of the screen in landscape orientation.No matter what I try, my custom keyboard layout stays confined in the safe area.What do you recommend?Thank you
