Is there a VSTS extension point for the account level hub group?

Is it possible to create a hub group as part of the account level hub group? I know I can add a collection admin hub group: ms.vss-web.collection-admin-hub-group (under the settings gear). I'm trying to add one after 'Users'. I searched, but I couldn't find anything pointing to this, so I'm not sure if it isn't possible or if the documentation is incomplete?

Solution

There is no way to add an extension with hub group shown after Users.

ms.vss-web.collection-admin-hub-group is already for account level hub group. But it only can be shown under settings.

And you can refer Hubs and hub groups for all the available hubs and hub groups in VSTS:
