bindkey to add?

[Gallagher]

hi guys

I want to make a bind when I press "f5" the createText1 disappear if I hit f5 again to reappear.

or is it not possible to do this with dx?

local screenWidth,screenHeight = guiGetScreenSize() 
  
function createText1 ( ) 
  
 if getElementData(getLocalPlayer(), "stamine") >= 6000 then 
    elementblood2 = dxDrawImage(screenWidth * 0.84, screenHeight * 0.85, screenHeight * 0.070, screenHeight * 0.070, "s8.png", 0, 0, 0, tocolor(250, 150,150)) 
    end 
  if getElementData(getLocalPlayer(), "stamine") >= 8000 then 
     
    elementblood1 = dxDrawImage(screenWidth * 0.84, screenHeight * 0.85, screenHeight * 0.070, screenHeight * 0.070, "s10.png", 0, 0, 0, tocolor(255, 255, 255)) 
    end 
     end 
  
function HandleTheRendering ( ) 
    addEventHandler ( "onClientRender", root, createText1 )  
end 
addEventHandler ( "onClientResourceStart", resourceRoot, HandleTheRendering )

local screenWidth,screenHeight = guiGetScreenSize() 
local render = false 
function createText1 ( )

     if getElementData(getLocalPlayer(), "stamine") >= 8000 then 
     
    elementblood1 = dxDrawImage(screenWidth * 0.84, screenHeight * 0.85, screenHeight * 0.070, screenHeight * 0.070, "s10.png", 0, 0, 0, tocolor(255, 255, 255)) 
    end 
end 
  
function HandleTheRendering ( ) 
 if render then 
    removeEventHandler ( "onClientRender", root, createText1 )  
    render = false
