How to get player.Character when holding a ProximityPrompt?

Hi!

I was wondering if you can use player.Character when holding a ProximityPrompt Or is there an other way to do this?

prompt.PromptButtonHoldBegan:Connect(function(promptObject, player)
 	if player.Character:FindFirstChild("Key") then
 		sound1:Play()
 	else
 		print("no key")
 	end
 end)

The script will play a sound if you have the keys for the door you have to open. So I need to check if the player has them.

try using prompt:InputHoldBegin() instead of prompt.PromptButtonHoldBegan
