Thanks, I can share the entire screen, I just want some way to share either a region of the screen or specific window. I have a hack that sets up a stream through the webcam but this is clunky and annoying to set up. Plus it means that the screen is shared as a webcam on messaging apps which doesn't always work too well (different people are highlighted as they talk). Sharing my entire screen isn't really that great as the resolution is 5120x1440 and it doesn't really display well for others.
