How would I implement an anti-team kill feature into my script?

I have this script for a hand axe that I'm making for a game, so far it works perfectly fine. Each time it hits a humanoid it deals damage. However I also want it so that it wont deal any damage to any of the player's team mates, and I have tried using GetPlayerFromCharacter however I am having trouble on figuring out how to use it in my code when the script detects that a humanoid has hit the handle.

Here is the snippet of my code that fixates on hit detection.

local canDamage = true
canChop = true
Tool.Handle.Touched:connect(function(hit)
	if not swinging then return end
	if not canDamage or not canChop then return end
	
	function damage()
		canDamage = false
		hit.Parent:FindFirstChild("Humanoid"):TakeDamage(26)
		Tool.Handle.FleshHit:Play()
		wait(coolDown2)
		canDamage = true
	end
	
	local function chop()
		canChop = false
		local chopValue = hit.Parent.ChopValue
		local addValue = 1
		chopValue.Value = chopValue.Value - addValue
		Tool.Handle.Chop:Play()
		wait(coolDown2)
		canChop = true
	end
	
	if hit and hit.Parent:FindFirstChild("Humanoid") then
		
		damage()
		
	elseif hit and hit.Parent:FindFirstChild("ChopValue") then --if hit tree then
		
		chop()
		
	end
end)

Before your damage script you can check if the person you are hitting is the same TeamColor or not, if they are then make damage 0, if not make the axe do 26 damage.
