Can't search on nested/embedded list of JsonModels

I have the following schema defined

class Workspace(JsonModel):
    id: str = Field(index=True)
    title: str = Field(index=True)
    users: List[User] = Field(index=True)

class User(EmbeddedJsonModel):
    id: str = Field(index=True)
    name: str = Field(index=True)
    type: str = Field(index=True)

I can't find an example like this in the documentation but if I had a Workspace saved how could I search for a User associated with that Workspace. From what I understand I have to start the search on Workspace and drill down to the users list.

From the documentation on the "skill" of a Person example I assume it would look something like this, but I haven't had success getting this to work.

user = Workspace.find(Workspace.users << User(**{"name": "John Doe"})).all()

Update/Edit.

The schema update to have User not be an EmbeddedJsonModel still doesn't function as expected, and no results are found.

The Migrator created a search index for both Workspace as well as User but it's not
clear how to take advantage of the User search index because no searches return values

class Workspace(JsonModel):
    id: str = Field(index=True)
    title: str = Field(index=True)
    users: List[User] = Field(index=True)

class Users(JsonModel):
    id: str = Field(index=True)
    name: str = Field(index=True)
    type: str = Field(index=True)

Stored Json

{
  "pk": "01GSWNGTT7WXD7NGHPN1XPGNQQ",
  "id": "6",
  "title": "Test Workspace",
  "users": [
     "0": {
       "pk": "01GSWNGTT7CMACEE55FSWKCVHQ",
       "id": "30",
       "name": "John",
       "type": "registered",
      }
   ]
}

User.find((User.name == "John")).all()

Returns "[]"

Reproduce the nested User lookup with Workspace.find(...) and the standalone User.find(...) example, then inspect the Migrator-created indexes and the search entry points. Done means searches return the expected Workspace or User records for the stored JSON, with the supported query form documented.
