You see your video as if it were in the mirror. So, if you show the text, it will appear backwards. Worry not, the rest of the participants see you and the text the way they should.
We mirror the image to make it comfortable for you. People are used to seeing themselves like that. Try that, raise the right arm, and the image will raise the hand on the same side, although it’s a left hand. If we don’t do that, your image will act unnaturally, disturbing you. That’s why the system works like a selfie or mirror.
