Describe the bug

Not a bug. But usage question discussion never gets an answer. So I am writing bug report.

As documentation suggest wrote selective sync function

my generated model

export declare class Door {
  readonly id: string;
  readonly index: number;
  ...
}

selective sync code

DataStore.configure({
  syncExpressions: [
    syncExpression(Door, (): ((post: Door) => any) => {       // <------ problem 1
      const s = (door: Door) => door.index('gt', 5)                  // <------ problem 2
      return s
    }),
  ],
})

problem 1

Argument of type '() => (post: Door) => any' is not assignable to parameter of type 'ConditionProducer<Door, []>'.
  Type '(post: Door) => any' is not assignable to type 'unique symbol | ProducerModelPredicate<Door> | Promise<ProducerModelPredicate<Door>>'.
    Type '(post: Door) => any' is not assignable to type 'ProducerModelPredicate<Door>'.
      Types of parameters 'post' and 'condition' are incompatible.
        Type 'ModelPredicate<Door>' is not assignable to type 'Door'.
          Types of property 'id' are incompatible.
            Type '(operator: keyof EqualityOperators<string> | "le" | "lt" | "ge" | "gt" | "beginsWith" | "contains" | "notContains", operand: string) => ModelPredicate<Door>' is not assignable to type 'string'.ts(2345)

problem 2
Type 'Number' has no call signatures.ts(2349)

I checked syncExpression type but no idea what it wants to be

export declare function syncExpression<T extends PersistentModel, A extends Option<T>>(modelConstructor: PersistentModelConstructor<T>, conditionProducer: ConditionProducer<T, A>): Promise<{
    modelConstructor: PersistentModelConstructor<T>;
    conditionProducer: ConditionProducer<T, A>;
}>;

Expected behavior

syncExpression to be typed

Reproduction steps

1. create new amplify project
2. setup data store
3. write selective sync code (https://docs.amplify.aws/lib/datastore/sync/q/platform/js/#clear-local-data)

Can someone tell me how to write this code in typescript strict mode? ( without any )

DataStore.configure({
  syncExpressions: [
    syncExpression(Door, () => { 
      const s = (door: Door) => door.index('gt', 5)
      return s
    }),
  ],
})
