To customize your scheduling page appearance, navigate to the Pages dashboard and use the ellipsis (...) to select Design & Settings.
The Design & Settings option will give you a range of other options, like updating the title and subtitle of your page, adding a logo, and updating your scheduling permalink as shown in the image below.
The right hand side of this window offers a preview of the welcome message and logo as they would appear on the live scheduling page. Click Save changes to apply your updates. To see your customized scheduling page in action, use the View Live button near the top of your Scheduling Pages screen to see the actual display that your clients will see.
