Feature Request: Handle MegolmEvents, request keys from other sessions

Dear Developers,
thank you for this nice command line utility. I have an encrypted 1on1 Chat that I would like to archive. Verification and room login has been successful. But the events received from the server are of the type "MegolmEvent", which is not handled. Any clues? I attached a sample of the event.
