Why we stop with Zoho Bookings en re-start Calendly

We were Calendly clients before we used zoho one. When we activated Zoho One we also had bookings included but because there is no automtic confirmation with a Zoom link we re-activated Calendly. Is this a right thinking process or can i do everything with bookings like with Calendly?
