Turning iPhone into an Airplay Video receiver

Now that we are back in non-virtual classrooms, I find myself missing the occasional iPad screen share to show an excerpt of a document or some random data that is not already in a keynote/PowerPoint slide.

I could solve this by hooking the iPad or even an Apple TV to the classroom’s projector and solve this, except for the fact that these projectors are quite old and use VGA ports.

I happen to have an old lightning to VGA adapter that I could hook my iPhone to and keep it there for as long as the class goes.

However, it doesn’t seem to be a way for me to mirror my iPad screen to the iPhone so it can act as a receiver for the old projector.

Is there an app that can help me bridge this?
