Video has a few mistakes
[Aug 5, 2022]: Release update was introduced in Spring '22 (not Summer '22)
Summer '22 has "View Concealed Field Data" permission replacing the "View User Records with PII" permission

An additional video is recommended only if you are a Privacy Center or Einstein Data Detect customer (who leverages the Compliance Categorization picklist) or enabled Enhanced Personal Information Management during Winter '22: https://salesforce.vidyard.com/watch/JnxBogZqsZTWkWQG7V7g5o?
