To share your report via a public link and allow all viewers to see chart data, which data source setting would you choose?

Choosing "Use owner’s credentials" ensures that anyone viewing your report via a public link can see the data, regardless of whether they have direct access to the underlying data source. The report will use the permissions of the report owner to fetch and display the data. "Invite user to view" and "Invite user to edit" are for specific users or groups, not for public links. "Use viewer’s credentials" would require each viewer to authenticate and have their own access to the data source, which is impractical and often impossible for public sharing.
