Do I should use the Configuration provider?

[NiKuma0]

This code works pretty well:

class Settings(BaseSettings):
    ...

class Container(containers.DeclarativeContainer):
    config = providers.Singleton(Settings)
    ...

I used pydantic settings, but I think this example can be used for any other settings library.

But providers.Confinguration has the from_pydantic method (and many other integration methods), for what? Should I use it instead of the Singleton provider? I just want to know the best practice and would appreciate any explanation)
