Can I use a command to change a leaderstat in game?

I made a group and I have a training center. I created a system where they receive points when they are doing good in the training. I just need a command that a team can enter to give them points. How would I do this?

This is the script I used to set up the leaderstat

game.Players.PlayerAdded:connect(function(player) 

local leaderstats = Instance.new("IntValue")
leaderstats.Name = "leaderstats"
leaderstats.Value = 1

local rank = Instance.new("StringValue")
rank.Name = "Rank"
rank.Value = player:GetRoleInGroup(4339656) 


local DataStore = game:GetService("DataStoreService")
local ds = DataStore:GetDataStore("PPSaveSystem")
local PP = Instance.new("IntValue",leaderstats)
PP.Name = "Progress Points"
PP.Value = ds:GetAsync(player.UserId) or 0

ds:SetAsync(player.UserId, PP.Value)
 PP.Changed:connect(function()
	ds:SetAsync(player.UserId, PP.Value)
end)

leaderstats.Parent = player
rank.Parent = leaderstats


end)

game.Players.PlayerRemoving:connect(function(player)
	 ds:SetAsync(player.UserId, player.leaderstats.Cash.Value)
end)
