Read documents

I am a new user, this app is running fine but I have 2 problems
1- in screen sharing mode , I would like to show a document to the webcam . But it appears written from right to left (hard to read in case you are not Leonard Di Vinci. Is there a way to horizontally flip the text and let anybody read the text ?
2- recording : I have tried no succes afert minutes , the recorded file does not appears
