the API only supported limited Filter types, can't flexible to support more filter types.

Forge-DM does have a filtering feature and documented here https://developer.autodesk.com/en/docs/data/v2/overview/filtering/ , but these API including GetHubProjects, GetHubs, GetFolderContents .etc are only supported limited filter types, for example, https://developer.api.autodesk.com/project/v1/hubs/b.a3d23eec-****-b932-fe63ecee08c3/projects?filter[name]=My Project are supported, but can not be supported by the PHP API.
I have checked with engineer, https://developer.autodesk.com/en/docs/data/v2/reference/http/hubs-hub_id-projects-GET/ is not correct about filter types, and more filter types can be supported without a problem.
