Copy Prolific ID to clipboard button: This script adds a green button in the upper right hand corner of the page that when hovered over will reveal itself and when clicked it will copy your Prolific ID to the clipboard allowing you to paste it.
You must edit this script with your own unique Prolific ID. Replace the words "ENTERYOURIDHERE" with your own Prolific ID in the code. An example is shown below.
navigator.clipboard.writeText('ENTERYOURIDHERE')
