I am setting up an event registration for an existing D8 website.
I have added content type Event with fields start date, end date etc. And I have a webform for event registration with computed token field set.
Which hook should I use to run a pre-render validation on event date and hide the webform.
PS: I don't want to close the webform as it will be reused for multiple events in future.
I did check this (and many), but its marked as outdated does it mean functionality is there in the webform module? https://www.drupal.org/project/webform/issues/2877082
