Overview
Vidyard has an integration that allows Drift chat to populate on Sharing Pages.
Solution
If Drift has been added to your Sharing Page as per the documentation, and when viewing the Sharing Page, Drift doesn't show up, it's possible that you have a Targeting setting blocking Drift from showing up. The most frequent restriction would be an URL, so make sure to include 'https://embed.vidyard.com/' inside the 'display when' URL list to ensure that Drift will not be blocked from being displayed on your Sharing Page.
