title: Drawer navigation inside Tab navigation but on top (react native)
body: <p>I'm coding a react native app similar to Instagram. I have already a bottom tab navigator with 5 items, the last one is the profile tab. </p>
  
  <p>Inside this profile tab I want a drawer navigator to manage the profile settings, I want this drawer only "drawable" inside this tab, not the others. But also I want the drawer to show on TOP of the tab navigator at the same time (just like instagram's).</p>
  
  <p>I am using the react-navigation library for this. My question is: is this possible? If yes, how could I implement it on my code?</p>
  
  <p>Thanks </p>
