How to delete Mail link from calendar event in iOS

I created a calendar event from an email which adds a link to the email. I wanted to delete the mail link and add a different website URL that has more information. But when I go to edit the event, there does not seem to be anyway to remove the email link (Show in Mail). Am I missing something?

You should be able to delete the original link by right clicking and using Cut. Then type in the desired URL.

That works on macOS, but I don’t see that it is possible on iOS or iPadOS.
