What is the best way to count values with Deno.Kv?

I want to show the total values in the database. It seems that the only way is with

kv.list()

kv.list()

and then iterate the values.

Probably this is not very performant if I only want to count the results. I'd like to have something like this:

const count = await kv.count(["users"]);

console.log(`There are ${count} users in the database`);

const count = await kv.count(["users"]);

console.log(`There are ${count} users in the database`);
