Maybe you could talk in front of the camera in front of a green sheet with your team and then screen record to sync up with it since not in a big room with a projector or maybe simpler if don’t have the equipment or space is just do like game streamers do and screen share with your face overlaid your desktop or switch back and forth. Sounds like doing a startup got to wear multiple hats including some video production.
For example there’s some YouTube vloggers who can talk to the camera like it’s natural but if they have to do any public speaking it feels different. I remember some channel I follow travel related was asked to speak at a meet up and then another YouTuber won a award and flew to New York to accept it. So you can talk to millions though the camera, but talking to a room with a few hundred or thousands is a bigger deal for some reason. Maybe because online more control and editing though... if you get sick or pronounce something wrong you could just edit it out and jump cut between
