Hello, i'm new to odoo and i'm currently working on the appointment module, i created few models such as appointment type, appointment slots etc. i want to see the all available appointment date and time in-short available slots in the user menu in the back-end same as in the appointment module in the run-bot. user can see the available time slots of the doctor in the user menu (back-end) and can book appointment from that available slot, how can i achieve this.
