Why is Lerp Not Working Correctly?

I have this NPC that when I'm near it and I press "E," then it's supposed to lerp the camera to face the NPC. It does face the camera where I want it, except it instantly puts it there instead of doing it smootly/lerping it.

Here is the part of the script with the lerp:()

Camera.CFrame = Camera.CFrame:Lerp(HMR.CFrame * CFrame.new(-4, 4, -7) * CFrame.fromOrientation(math.rad(-20), math.rad(215), 0), 0.07)

UIS.InputBegan:Connect(function(input)
		if input.KeyCode == Enum.KeyCode.E and Detected.Value == true then  	 
            DetectedNPC == NPC  then --Chatting.Value == true then
			--for i, NPC in pairs(NPCs:GetChildren()) do 
			local Humanoid = DetectedNPC:FindFirstChild("Humanoid")
			local HMR = DetectedNPC:FindFirstChild("HumanoidRootPart")
			
			if Humanoid and HMR then
				Camera.CameraType = Enum.CameraType.Scriptable
				Camera.CFrame = Camera.CFrame:Lerp(HMR.CFrame * CFrame.new(-4, 4, -7) * CFrame.fromOrientation(math.rad(-20), math.rad(215), 0), 0.07)
				game.Players.LocalPlayer.Character:WaitForChild("Humanoid").WalkSpeed = 0
				game.Players.LocalPlayer.Character:WaitForChild("Humanoid").JumpPower = 0
			end
		end
	end)
	

And here is the full script:

Help would be appreciated thanks.
