Prerequisite: If you want to show widgets exclusively for mobile view, you must first add widgets for desktop view under Advanced > Widgets.
Now, navigate to the Mobile view section and toggle on Enable Mobile view. This adds two new tab options on the top bar; Desktop and Mobile expo.

Widgets: This shows all the widgets that you’ve added to the desktop view. Widgets can only be added in the desktop view. However, once added, you can hide/unhide widgets exclusively for mobile view.
Editing or deleting a widget for the mobile view will also edit/delete it for the desktop view and vice-versa.
A right-side preview pane shows all the changes you made in real time.
