IOS developer needed

Hello! I need to bridge the method called addBoundaryTimeObserver (https://developer.apple.com/documentation/avfoundation/avplayer/1388027-addboundarytimeobserver) in this react native library https://www.npmjs.com/package/react-native-audio-recorder-player so that I can give a time in seconds and call back function to be executed on the react-native side. Thank you.
