The content of your HighQ site may be highly sensitive or permissioned, and the integration may be purely to extract data and summarise files, without providing access to other users, or the ability to use content with other skills or processes.
Conversely, the site content or purpose may require flexibility, allowing users to use and process files not only with the integrated skills but also with other skills, such as Document Comparison or Timelines, or to search a database populated from the site in a contextual, natural language.
