GraphQL - Query current user and custom user settings

[gvkries]

Is your feature request related to a problem? Please describe.

Getting information about the current user and additionally its custom user settings (aka user profile) is currently not possible out of the box with GraphQL.

Describe the solution you'd like

A query as described in the documentation (https://docs.orchardcore.net/en/latest/docs/reference/modules/Apis.GraphQL/#http-methods-headers-and-body) would be handy for using OC as headless CMS with frontend users. This can then also allow querying custom user settings (i.e. content types with CustomUserSettings stereo type).

A sample query could look like:

query MyQuery {
  me {
    email
    phoneNumber
    userName
    userId
    userProfile {
      name
      profilePicture {
        urls
      }
    }
  }
}
