Add something to index DB, Browser don't allow direct modification of index DB from dev tools so you need to run a script like this.

addToIndexedDB.js

const addToIndexedDB = async (dbName, version, storeName, keyPath, key, value) => {
  try {
    // Open a connection to the database
    const dbRequest = indexedDB.open(dbName, version);

    dbRequest.onupgradeneeded = (event) => {
      const db = event.target.result;
      // Create an object store if it doesn't exist
      db.createObjectStore(storeName, { keyPath });
    };

    // Handle success and failure
    dbRequest.onsuccess = (event) => {
      console.log("Data added successfully:", event.target.result);

    const db = dbRequest.result
    const transaction = db.transaction(storeName, "readwrite");
    const store = transaction.objectStore(storeName);

    // Add the key-value pair to the object store
    const request = store.put( value, key);
    };

    dbRequest.onerror = (event) => {
      console.error("Error adding data:", event.target.error);
    };

    await transaction.complete; // Ensure transaction completion
  } catch (error) {
    console.error("Error accessing IndexedDB:", error);
  }
}
