Workspace users highlight the times they would be willing to have a meeting, then enter the appointment duration and location (or a Google Meet room) and add a title and description. This will fire up a UI that can be used to create an appointment webpage.

Workspace users will soon be able to pick the 'Appointment Schedule' from the 'create' appointment button. You present the periods you're willing to have a meeting, and the other user will be able to pick a time. Google announced Friday that users will soon be able to create a 'booking page' UI they can send to anyone they want. Google Calendar's latest update promises to take a lot of the back-and-forth out of booking appointments.
