Bookings- Button to allow clients finish their registration on an external website

**Is it possible to add a button that allows users to finish their registration in a third-party site? ** This is for Bookings in Wix Studio Editor. Of course, after getting a premium plan that allows payments.

I have guest instructors and I would like to not charge their fee in their behalf. I would like to implement a dedicated button that enables clients to seamlessly complete their registration on another website. This enhancement aims to streamline the experience for both the instructors and clients, ensuring a smooth transition and accurate tracking of fees associated with guest instructors.

The option is in the Events wix app but not in bookings.
