DestinationMiddlewareFunction type is missing from export

[antgonzales]

I'm currently trying to create a Destination Middleware Function outlined in this guide:
https://segment.com/docs/connections/sources/catalog/libraries/website/javascript/middleware/

The current @segment/analytics-next library supports importing the general MiddlewareFunction type but does not support DestinationMiddlewareFunction.

Here's how I want to use the type:

import type { DestinationMiddlewareFunction } from '@segment/analytics-next';

export function destinationMiddlewareFactory(): DestinationMiddlewareFunction {
  return function destinationMiddlware({payload, integration, next}) {
    ...
    next(payload)
  }
}

I'm currently using "@segment/analytics-next": "^1.53.3".

Here is the type in the sourcecode:

analytics-next/packages/browser/src/plugins/middleware/index.ts

Line 23 in 9ba0dc6

export type DestinationMiddlewareFunction = (
