Voice Dictation/Whisper Input Mode (Codex App on iPhone/iPad/iOS)

What feature would you like to see?

Currently, Codex iOS does not have a dictation feature that I'm aware of:

It would be great to have a dictation feature for Codex app on iPhone/iPad/iOS.

Same/similar to the dictation feature in a new chat or on the Codex Web:
