MobileRTCRawData No License

Hi Zoom Team,
I am using zoom sdk meeting for android. i want to access meeting audio data but when i subscribe audio data receive delegates i am facing following error. MobileRTCRawData_No_License. Please tell me how can we solve this problem.

i am using zoom-sdk-android-5.17.11.20433 in my app

@m.mudasir you should not need a license anymore if you are trying to access raw audio / raw video.

However you do need to call “startrawrecording” first before subscribing.

@chunsiong.zoom I have read meeting sdk documentation and not found any startrawrecording function or something related to it. Please help me how can i fix MobileRTCRawData_No_License Issue. I have also subscribe IZoomSDKAudioRawDataDelegate listener.
