How can I use callback that returns Promise?

I have function:

export const paramsFactory = (params: paramsType) => {
  return ...
}

In another component I have the same function but after return … it also contains await getPageInfo({ page: 1 }).
So I need pass callback as a second param to this function. And how to use it correctly?
I have something like that:

    export const paramsFactory = (params: paramsType, callback?: () => Promise<void>) => {
      return async (...) => { 
        ...
        if (callback) {
          await callback()
        }
      }
    }

await callback() as a part of return statement.
When I use it paramsFactory(params, getPageInfo({ page: 1 })) I get

TS2345: Argument of type ‘Promise’ is not assignable to
parameter of type ‘() => Promise’.   Type ‘Promise’
provides no match for the signature ‘(): Promise’.

>Solution :

use

paramsFactory(params, () => getPageInfo({ page: 1 }))
