That is what ‘automation’ often is. You take a working process, then let machines do as many steps in that process as you can. Harvesting crops, sending memos, robots spraypainting car parts, self driving cars (We still have a lot to do there)
Building on that it gets even more interesting as we try to find better, or even completely new processes.
I use https://owlbear.rodeo/ for that. It allows you to cast your map to a 2nd screen in player mode, while you can still see the full picture. It has ‘fog’ to hide areas from the players and supports zooming in on each screen separately, or you can sync zoom&view (manually or continuously) from your dm screen
