Hello @admohamed and welcome to the Community!
From Overview in your dashboard, you can see your pending and upcoming appointments as well as client messages at a glance.
To confirm a pending appointment, click Decline or Accept. Your client will be notified of your response.
Click any upcoming appointment to view the appointment details, make changes, or cancel the appointment.
You can also accept appointments directly from Calendar. Pending appointments appear on your calendar. Click any pending appointment and click Accept or Decline.
Hope this helps!

This is the setting I am referring to here:

And here is the legend for how appointments will look when your customers book but their appointments aren't confirmed:

I hope this information is helpful!
