Perhaps, let me try and share some more insight, I have a front end form which people fill in to customise a profile on the front end too. I would like the https://instagram.com/ to be filled in the field before they even touch the form but not visible. So I can then label the field “instagram username” when they put there username in it creates the value https://instagram.com/username for a button to be clicked and redirected to their instagram profile.
