Power BI Content packs allows users to package your dashboards, reports and datasets and share it with entire organisation or specific groups (users within organisation). This also allows the users to enhance the dashboards within the content packs.
Power BI Content Packs are available only if the users have Power BI Pro. Publishing an organizational content pack adds it to the content pack gallery. This centralized repository makes it easy for members to browse and discover dashboards, reports, and datasets published for them.
