Ability to @mention all community members while editing a document

Currently by default, when editing a community file (document) in IBM Docs, only the community owner appears listed during attempt to @mention another editor within a comment of a document.  The current getUserList method used during the Docs Editor API call only gathers a list of users who have actually performed edits, thus deeming them editors of the document, to the document.  However, community owners have the option to give all community members editor access to files which may mislead users to believe they are already designated doc editors of a community file.  

Request is for Docs team to develop API call that will determine if all community members are given editor access to files and then gather that list of users/editors for the @mention feature used while commenting a document.
