Dear Sir or Madam: I am writing to ask about the url scheme to open miceophone. Because our Line Bot provide the audio message serve and want to support a quickly open miceophone function with richmenu to help user send an audio message. I have checked all the overt LINE URL schemes, and can't find it. If it is possible, could you help to offer the quickly way to open miceophone by any possibility.
I look forward to hearing from you. Your faithfully,
