Lack of close button on Add restaurant overlay (Enatega multivendor admin app)

Is your feature request related to a problem? Please describe.
Add restaurant overlay gets closed when a user clicks outside the overlay. This can be by mistake but the user looses all the filled-in infos.

Describe the solution you'd like
Provide CLOSE button on the overlay, instead of closing it by the click outside the overlay.

Additional context
Add any other context or screenshots about the feature request here.

Start by locating the Add restaurant overlay in the React Native admin app and inspect how it currently closes when the user taps outside it. Add the requested CLOSE control while preserving the entered information when an outside tap occurs. Done means the overlay can be closed explicitly and accidental outside taps no longer discard the form.
