Wait For 2 Players script, Adjustments needeed. Any help?

My script works great actually :D. It waits till there is atleast 2 players in the server. My game has 4 different teams for 4 different reasons. The 2 that matter in this script are 'Medium stone grey' and 'Institutional white' When your on the institutional white team, you are either in the menu or in the tutorial and the game doesn't affect you. When you are on the Medium stone grey team you are in the lobby and ready to play. I am wanting this script to wait for atleast 2 players on the Medium stone grey team and not 2 players in the server.

Here is my script:

while true do 
wait(2)
if game.Players.NumPlayers < 2 then
	game.Workspace.Message:Remove()
	local h = Instance.new("Hint")
h.Parent = game.Workspace
h.Text = "Need Atleast 2 Players to Play"
elseif game.Players.NumPlayers > 0 then
	game.Workspace.Message:Remove()
	game.ServerStorage.LobbyTimer:Clone().Parent = game.Workspace
	wait(62)

Yes instead of using a repeat wait I used while true do, which needs to stay there. I have the script removing a hint and re-making it into workspace. Which it just cycles and adds a hint then removes it over and over. Which could be not the best way to do it. If you do want to add a reapeat wait feel free to do so, However leave the while true do there for other purposes.

EDIT: I used your script and edited to my liking (So it works the way I need it to)

wait()
while true do 

local NumPlayers = 0  
 
for _, Player in pairs(game.Players:GetPlayers()) do 
 
if Player.TeamColor == BrickColor.new('Medium stone grey') then
	wait()  
		NumPlayers = NumPlayers + 1  
	end  
if NumPlayers <  2  then
	wait(.5)
		game.Workspace.Message:Remove()  
			local GameHint = Instance.new("Hint") 
				GameHint.Text = "Need Atleast 2 Players to Play"  
					GameHint.Parent = game.Workspace  
elseif NumPlayers >  0  then
		wait(.5)
			game.Workspace.Message:Remove()
				game.ServerStorage.LobbyTimer:Clone().Parent = game.Workspace 
					wait(62)

after the wait 62 other things in the script happen, but however it is too much script to enter into this :p
