Package not found after npm install

[TheCheddarCheese]

Hi, I tried installing the utaformatix-ts package with npm:

npx jsr add @sevenc-nanashi/utaformatix-ts

It shows up in my package.json, but when I try to compile my TS files I get this error:

src/convert.ts:1:25 - error TS2307: Cannot find module 'jsr:@sevenc-nanashi/utaformatix-ts' or its corresponding type declarations.

import { Project } from "jsr:@sevenc-nanashi/utaformatix-ts";

What does your tsconfig.json look like?

Do I have to add something? I didn't see anything about that in the docs
