FYI the SDK already supports passing arbitrary parameters to any request: https://github.com/auth0/Auth0.Android/blob/3.8.0/auth0/src/main/java/com/auth0/android/request/Request.kt#L57
This is why none of the other methods in the Authentication API client support an explicit "organization" argument.

If you prefer to add an explicit argument for this, consider adding the argument to all the other (relevant) methods of the Authentication API client.

The idea was to explicitly say that a user can be added to an org while signing up and signing in with passkeys. Hence added to only these two api end points. I am aware ,we can add it as an additional parameter to the request object, but felt this would be more clearer with the intention. If that is not required, there is no additional changes required on SDKs and we just needs to call this out in the docs
