Set default sharing link to "People with existing access"
Is it possible to set de deafutl sharing link to "People with existing access" at organization-level? Didn't find this option athttps://docs.microsoft.com/en-us/sharepoint/turn-external-sharing-on-or-off#file-and-folder-links. Also, at this section, there's a note"This setting specifies the default for your organization, but site owners can choose a different default link type for a site.", but I can't find how to do it (as site owner, not sharepoint admin). Can someone help?
