I am using this app as an easy way to add an unsubscribe link to emails send from SFDC. Everything works great but at the end of the unsubscribe process (which is a flow) I get the annoying screen saying "Your flow finished".
As I have another screen in the flow saying that the unsubscribe process went well, I tried avoiding the problem by hiding the footer on such screen, so the user wouldn't see the finish button and couldn't go further and therefore the flow finished screen would never be shown.
However, for some reason I don't really understand, the finish button still shows up.
So I had a look on the web and found this, which seems to be exactly what I need. But I don't really understand where to find this URL that should be edited. I tried editing the flow properties but there's no option to edit such link.
Could someone show me the steps to achieve this? Or advise for another solution anyway?
Thanks!
