How to customize "Booking Summary" for clients?

How to customize "Booking Summary" for clients?

We're embedding Zoho Bookings into our website. The Modern View looks great and matches our website fonts and style. But after a client books an appointment, the "Booking Summary" view doesn't. Is there a way to customize this view? For example, we don't need a "Booking ID" to be shown to the client. Way to hide it? Way to customize labels, styles, etc?

Thanks for any help :)
