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.

The issue names the Add restaurant overlay but no file, test, or entry point. Search the admin app for the Add restaurant form, then inspect how the overlay closes and how its current outside-click behavior is tested. Done means users can explicitly close the overlay without losing entered information through an accidental outside click.
