    message = document.getElementById("clear-storage-message")
    message.innerText="Running"
    window.indexedDB.open('JupyterLite Storage').onsuccess = function(e) {
        // There are also other tables that I'm not clearing:
        // "counters", "settings", "local-storage-detect-blob-support"
        let tables = ["checkpoints", "files"];

        let db = e.target.result;
        let t = db.transaction(tables, "readwrite");

                }
            }
