I've been trying to created a managed folder of bookmarks/favorites deployed via Configuration Profile to Microsoft Edge.
It isn't available via the JSON custom schema.

 
I've uploaded this plist, borrowed from Talking Moose, using the com.microsoft.edge domain.

 
This info outlines how the setting should work:
https://docs.microsoft.com/en-us/deployedge/microsoft-edge-policies#managedfavorites
Maybe I'm missing how to make the setting "mandatory".
Thanks for any help.
