Deno not recognizing default export from npm package 'unstorage' as a function

Hello everyone, I am attempting to set up unstorage with the Deno KV driver, as per https://unstorage.unjs.io/drivers/deno When I import the driver and attempt to call it, the LSP reports that denoKVdriver lacks a call signature, and type-checking also fails:

This expression is not callable.
  Type 'typeof import("file:///home/vince/.cache/deno/npm/registry.npmjs.org/unstorage/1.16.0/drivers/deno-kv")' has no call signatures.deno-ts(2349)

This expression is not callable.
  Type 'typeof import("file:///home/vince/.cache/deno/npm/registry.npmjs.org/unstorage/1.16.0/drivers/deno-kv")' has no call signatures.deno-ts(2349)

If I invoke denoKVdriver.default(), the LSP no longer reports the error, but type-checking still fails. Relevant d.ts:

import type { Kv } from "@deno/kv";
export interface DenoKvOptions {
    base?: string;
    path?: string;
    openKv?: () => Promise<Deno.Kv | Kv>;
}
declare const _default: (opts: DenoKvOptions) => import("..").Driver<DenoKvOptions, Promise<Deno.Kv | Kv>>;
export default _default;

import type { Kv } from "@deno/kv";
export interface DenoKvOptions {
    base?: string;
    path?: string;
    openKv?: () => Promise<Deno.Kv | Kv>;
}
declare const _default: (opts: DenoKvOptions) => import("..").Driver<DenoKvOptions, Promise<Deno.Kv | Kv>>;
export default _default;

Code:

import { createStorage } from 'unstorage';
import denoKVdriver from 'unstorage/drivers/deno-kv';

export const storage = createStorage({
  driver: denoKVdriver({}),
});

import { createStorage } from 'unstorage';
import denoKVdriver from 'unstorage/drivers/deno-kv';

export const storage = createStorage({
  driver: denoKVdriver({}),
});

Is there a way to work around this?
