SharePoint site collections has different types, including Team Site with an Office 365 Group, Communication Site and Team site without an Office 365 Group and so on.
This query: SPSiteURL starts with https://(tenant).sharepoint.com/ will not return Team Site with an Office 365 Group.
Please create a new Adaptive Scope with Microsoft 365 Groups type to return Team Site with an Office 365 Group.
The query in the Adaptive Scope returns the same results as the search query.
