Magic keyboard not working with Zoom screen shared with me.

This question is much the same as found here: https://discussions.apple.com/thread/252831355

I have been using my iPad in Zoom meetings, and I normally type with the attached Magic Keyboard. All is fine for writing in the chat window, etc. However, if someone is sharing their screen or sharing their whiteboard, the physical keyboard does not function. I can bring up the on-screen keyboard by pushing the right on-screen buttons, but this covers up half the screen and usually covers up over the space I am trying to type. I also notice that, when the other person is sharing their screen, I cannot use my physical, Magic keyboard to type in the chat window. And yet, the tracking pad still works, and I can draw on the shared screen with the tracking pad on the Magic Keyboard, while the Keyboard itself fails to work.

However, the reverse situation is not true. If I am sharing my screen, I can annotate with my Magic keyboard.

This is the only situation I have found where the Magic Keyboard becomes unresponsive, so it is certainly a software issue. Nothing on the Zoom website helps explains the problem.
