How do I make a lobby where the player spawns on a podium?

I want to make a lobby for my new game, Battle Bounty.

There will be two other games connected to it, besides the lobby. So, that's three in total. I've already got the two other games connected.

I want my lobby to be that when a player joins, I want them standing on a podium, like I see in a few other games online. When they're on the podium, and you can examine your character, etc, I want there to be buttons on the side.

Ex)

[Play] [Info] [Customize] (Player is standing here)

                                                   [Rank]
                                                  [Exp level]

If you could tell me how to do this, that'd help me out a lot, thanks!
