Add to Calendar button passed with Query String (Redirect URL)

Hey, how is it possible to use the {{add_booking_to_calendar}} in Redirect URL? I want to use a custom thank you page, but I don't know how to use Add to Calendar button on that custom page.

The URL looks like:

https://abc.com/thank-you/?button=%3Ctable%20style=%22margin:%200%20auto;%20border:%20none;%22%3E%3Ctbody%3E%3Ctr%3E%3Ctd%20style=%22border:%20none;%20font-size:%201rem;%22%3ELisa%20kalendrisse%3C/td%3E%3Ctd%20style=%22border:%201px%20solid%20black;%20padding:%205px%205px%200%205px;%22%3E%3Ca%20href=%22https://calendar.google.com/calendar/r/eventedit? ....

It's very long and it's not working with Elementor's Dynamic Tags -> Request Parameter.
