Hello.
Its possible in the paid versions of Booking Calendar to use secret links for editing or cancellation of own bookings.

If you need to show for users all past bookings of this user, then check here: https://wpbookingcalendar.com/help/user-bookings-listing-video-tutorial/

Please check this FAQ instruction how to configure ability to edit or cancel own booking(s) of visitor, who made these booking(s): https://wpbookingcalendar.com/faq/configure-editing-cancel-payment-bookings-for-visitors/

You can test Booking Calendar live demos at this page https://wpbookingcalendar.com/demo/ to be sure in functionality and do not have misunderstanding.
Kind Regards.
