Difficulty with using Braille Edge 40 as keyboard for iPad

Braille on Apple Products

My colleagues and I have been sharing an issue.

When we are using a Braille Edge as a refreshable braille display using VoiceOver with an iPad running iOS 12, we can get the text being typed on the 6 key braille input to speak through Voice Over but we are not able to get the text to show up in any of the apps that we are using.

Can anyone provide advice or assistance in how we overcome this?
