My hands were visibly shaking on a video call interview and I just said so out loud

Couldn't type steadily, could see it on the screen share, and figured pretending it wasn't happening would make it worse. Said something like "sorry, bit of nerves, one sec" and took an actual breath before continuing. Interviewer just waited, no reaction either way. Didn't get that offer but a later one did come through, and I think the honesty cost me less than the alternative would have.
