How can I modify It so whenever your on a team, you cannot damage your team mates?

As the name says, I was wondering how I can modify the script so It won't damages players If there one your team (Btw the gun name Is SI2010 (The SI means "Skill Issue"))

Script:

local tool = script.Parent

---Sounds---
local ShotgunSound = tool.FireSound

---Animation---
local Shot = tool.Shot

---Other stuff---
local debounce = false

tool.Activated:Connect(function()
	if not debounce then
		debounce = true
		ShotgunSound:Play()
		local Char = tool.Parent
		local Hum = Char.Humanoid

		local AnimationTrack = Hum:LoadAnimation(Shot)
		AnimationTrack:Play()
		local MeshPartPojectile = Instance.new("MeshPart")
		local VectorForce = Instance.new("VectorForce")
		local Attachment = Instance.new("Attachment")
		
		MeshPartPojectile.Parent = game.Workspace
		MeshPartPojectile.Size = Vector3.new(1,1,1)
		MeshPartPojectile.TextureID = "http://www.roblox.com/asset/?id=5694989372"
		MeshPartPojectile.Position = tool.Handle.Position
		MeshPartPojectile.Orientation = tool.Handle.Orientation
		VectorForce.Parent = MeshPartPojectile
		Attachment.Parent = MeshPartPojectile
		VectorForce.Attachment0 = Attachment
		VectorForce.Force = Vector3.new(0,300,-6000)
		MeshPartPojectile.Touched:Connect(function(hit)
			local humanoid = hit.Parent:WaitForChild("Humanoid")
			if humanoid then
				humanoid:TakeDamage(10)
				local UNDERTALE = Instance.new("Sound")
				
				UNDERTALE.Parent = humanoid.Parent.Torso
				UNDERTALE.Volume = 10
				UNDERTALE.SoundId = "rbxassetid://406913243"
				UNDERTALE:Play()
				MeshPartPojectile:Destroy()
				game:GetService("Debris"):AddItem(UNDERTALE,0.5)
			end
		end)
		game:GetService("Debris"):AddItem(MeshPartPojectile,5)
		game:GetService("Debris"):AddItem(VectorForce,5)
		game:GetService("Debris"):AddItem(Attachment,5)
		wait(1)
		debounce = false
	end
end)

You can use player.TeamColor to check their teams.

Use something like this before damaging them to stop the script from taking their health away.

if (player.TeamColor == otherplayer.TeamColor) then
print('same team')
return
end
