Is there a way to make a progress bar for replicated actors?

I have a game where the world’s surface is divided into chunks like minecraft and there are possibly existing npcs at random locations. A player can join the level at any time.

I want to create at a minimum a loading screen for the player when they first connect that will contain a progress bar that will progress through the number of actors waiting to be replicated to the client.

I have seen tutorials on how to create a loading screen for static levels where the geometry and actors are defined in the level file, but this seems to be a case where I am more interested in knowing about the replicated actors than about the level.

I have spent a few days between other tasks trying to google a starting point for this, but I keep getting the same useless posts. I am looking for some direction so I can progress on this.

Please and thank you.
