My Pastor asked for help and I'm lost

My Pastor asked me to help figure out the projector program. I’ve never used this software and i can’t seem to find any tutorials online. He has Quelea 2021.0 and a projector. I can’t figure out how to put the presentation on the projector. Right now the full PC screen is projected to the screen behind the pulpit. If anyone is willing to offer guidance it would be greatly appreciated

If you are unable to find help locally, I could help you some using a remote TeamViewer connection (no charge). I set up and configured Quelea on our church PC.
