Pydantic compatibility and validation_alias

[kondera]

From my tests I couldn't create document's Field with validation_alias. I could create one with alias e.g.:

class Nested(Document):
    some_field: int

class ModelInDB(Document):
    main_field: int
    nested: Nested

class ModelForQuery(Document):
    # this works main field
    changed_name: Annotated[int, Field(alias="main_field")
    # this doesn't :/
    # main_field_changed: Annotated[int, Field(validation_alias="main_field")]
    # also would be pretty cool to be able to get into nested field with alias path
    # field_in_nested: Annotated[int, Field(validation_alias=AliasPath("nested", "some_field"))]

I have big docs that have many keys, but I don't need to get whole doc, so I would like to be able to create smaller models that change names of some fields, but I sometimes need to access some field from nested dict (that's why usage of AliasPath).
I read that beanie is compatible with pydantic so I thought that validation aliases would just work.

Is there some way to do it another way? I guess I try to create bigger models that have some property fields for easier access, but I don't know if this is the best way to do it.
