How to use Deno KV when deploying Next.js to Deno Deploy?

I do not see a straightforward way to use Deno KV inside a Next.js project deployed to Deno Deploy:

-

Deno.openKv()

Deno.openKv()

Deno.openKv()

Deno.openKv() won't work -> Deno is not found.
-

import { openKv } from "@deno/kv"

import { openKv } from "@deno/kv"

import { openKv } from "@deno/kv"

import { openKv } from "@deno/kv" +

await openKv("URL")

await openKv("URL")

await openKv("URL")

await openKv("URL") won't work either -> The Next.js app just won't build with this dependency.

Am I missing something?
