How to ref a schema that was not defined by typebox?

[OmarAlkadri]

How can I create a userID whose reference is the same as users

i use feathersjs V5 and typeBox

export const usersSchema = Type.Object(
{
_id: ObjectIdSchema(),
email: Type.String(),
date: Type.String({ format: 'date' }),
password: Type.Optional(Type.String()),
userID: ObjectIdSchema(),

user: Type.Ref(usersSchema),
},
{ $id: 'Users', additionalProperties: false }
)
Block-scoped variable 'usersSchema' used before its declaration.ts(2448)
users.schema.ts(13, 14): 'usersSchema' is declared here.

Hello, we have been using feathersjs for a long time and now we want to move to feathersjs V 5, but I am now creating an experiment project and I am facing a lot of problems.
The most important of which is that I cannot create a reference from the same service
I am having problems sending parameters to the hooks I created
Can you please suggest me some solutions?
