Hello @Mavash0
Here is the Airbnb link on the subject to help you:

You'll read that Airbnb only update the synched calendars every two hours so just be aware that this makes double bookings possible! So updating your calendars manually is necessary too. Read up on the cancellation policy as a host to avoid the penalties😉
All the best
