Responding to Chat after the Fact

During our Webinar, we had a few good questions come through our chat - sent to hosts/panelists only - we did not have time to address them, but I'd like to respond to them now, after the fact. I can't seem to find the chat again. In the recording chat file, I only have the 2 chats that were sent to everyone at the very end. The ones that engaged in the middle of the webinar are not there. Is there any other option to finding these folks?
