How do you solve, archive and bring back your physical Whiteboard sessions?

A burning question from a whiteboard addict for all our teams. Whether its UI/UX, Roadmapping features, Sales.. we currently snap a photo and share it to our WhatsApp/Teams/Slack channels depending on the team. The problem here is we're mostly NEVER able to retrieve the relevant whiteboard discussion at the time we most need it. How are you guys solving this?
