Vanity URL for pending worker notifications

Summary: Vanity URL for onboarding

Content (please ensure you mask any confidential information): We have a requirement that when a pending worker is created, the email going out to those pending employees should have vanity URL. We ideally would not want to give access to the current URL being used by us. I would like to know if someone has achieved this requirement before. If yes would appreciate if a document with all steps can be shared
