I have two webforms on my Drupal 8 website. When a user submits the first webform, I have the confirmation redirect set to a second webform. I would like to populate one of the fields in the second webform with one of the submitted values from the first form. I have it set up as two separate webforms as some users will by-pass the first form and go directly to the second webform where they can manually enter the content into the field I need populated. Any idea how I can achieve this?
