Sensitivity Labels & Default sharing link type

You can configure the default sharing link type for SharePoint and One Drive for Business in the SharePoint Admin Center:

With PowerShell you now can associate a default sharing link type to a sensitivity label.
Example:
If you have a label called "TOP SECRET". You could already configure this label to stop external sharing on sites associated with this label:

Now you can fine tune even this and specify the default sharing link type usingt PowerShell:

• Set-Label -Identity 'TOP SECRET' -AdvancedSettings @{DefaultSharingScope ="SpecificPeople"}

• Set-Label -Identity 'TOP SECRET' -AdvancedSettings @{DefaultShareLinkPermission ="Edit"}

This feature is now (06/08/2021) in public preview.
