How to toggle an Options Frame if the player isn't typing help?

I created a script that would open/close an Options menu when pressing the "O" key on your keyboard. However, when I tried typing inside a TextBox that the frame "menu" had inside it, it would cut off the menu when I pressed "O". Here's the script:

local uis = game:GetService("UserInputService")
uis.InputBegan:connect(function(input)
	if input.UserInputType == Enum.UserInputType.Keyboard then 
		if input.KeyCode == Enum.KeyCode.O then 
			print("Success!")
			local menu = script.Parent.options.menu
			local open = menu.isOpen
			if open.Value == true then -- Menu is open
				menu.Visible = false 
				open.Value = false 
			else -- Menu is not open 
				menu.Visible = true 
				open.Value = true 
			end
		end
	end
end)

The problem is that this script is triggered when "O" is pressed, even when a player is typing in the radio. How do I make this script connect the function when the player is not typing?

local uis = game:GetService("UserInputService")
uis.InputBegan:connect(function(input,gameprocessed)
	if gameprocessed == false then
		if input.UserInputType == Enum.UserInputType.Keyboard then
			if input.KeyCode == Enum.KeyCode.O then
				print("Success!")
				local menu = script.Parent.options.menu
				local open = menu.isOpen
				if open.Value == true then -- Menu is open
					menu.Visible = false
					open.Value = false
				else -- Menu is not open
					menu.Visible = true
					open.Value = true
				end
			end
		end
	end
end)

When the focus is on a gui then gameprocessed will be true. The function will be fired when the focus is not on a gui, so when gameprocessed is false.
