How to add a custom button to copy URL to clipboard?
I'm using RH2020, frameless output.
How do you add a button to the row of topic page buttons that copies the URL of the current topic to your clipboard? Right now, I've got the out-of-box functionality working where you click the Share button, and the share panel appears with an option to share via email. Sharing via email opens your email provider in a separate browser with the link to the topic pre-populated in an email draft.
However, our customer support team wouldn't just share using an email - their responses need to be sent through our ticketing system. All I really want is for them to click the Share button, and for the link to be copied to their clipboard instead so that they can paste it into their response in a ticket.
How do I make that happen? Thanks in advance!
