Currently, this functionality is only available on the Android application.
How can I add (or hide) the option of adding a booking in my calendar?
1. Select "Settings" from the menu.
2. In the "Settings" window, select "Add a booking in my calendar" (and if you want to hide this functionality, unmark this option).
After selecting this option, a button will appear in your calendar enabling you to add bookings without having to indicate the date and room earlier.
