Couldn't you also pose/answer the questions during prep using the Chat option that allows staff questions? Then the list is already on the board and you should be able to recycle the answers.
We face this as well. No matter how many times you state or write that the presentation will be shared, the link to the handout is X, no recording -whatever - someone then individually asks.
Sometimes I key information, like a URL in staff chat so I can easily grab it for copy/paste if the question is asked.
