I'm using firebase for a SvelteKit project. I'm getting the following error only after reloading:

getApp is not defined

from the file /src/routes/admin/index.svelte:

import { initializeApp, getApps, getApp } from "firebase/app";
import { getFirestore } from "firebase/firestore";


    const firebaseConfig = {
    // (config info)
};


    const firebaseApp = 
    (getApps().length === 0 ? initializeApp(firebaseConfig) : getApp());

    const db = getFirestore();

    const colRef = collection(db, "questions");

Why does firebase work until I reload? I'm guessing it's something to do with the fact that only the first page load is server rendered? Does getApp() not work on the client?
