Help me with my code I'm trying to delete data from firebase but I'm getting reference error

function showNotes(){
    let html = "";

    let notesElm = document.getElementById('notes');

    get(child(dbRef,"Notes")).then((snapshot) => {
        var count = 0
        if (snapshot.exists()) {
            const noteData = snapshot.val()
            for (const item in noteData) {
                if (Object.hasOwnProperty.call(noteData, item)) {
                    const element = noteData[item];
                    html+=`
                    <div class="card mx-2 my-2 noteCard" style="width: 18rem;">
                    <div class="card-body">
                    <h5 class="card-title">${element.title}</h5>
                    <p class="card-text">${element.text}</p>
                    <button id=${count} onclick="deleteElement(${element.title})" class="btn btn-primary">Delete Node</button>
                    </div>
                     </div>
                     `;
                    }
                    count++
                }
                notesElm.innerHTML = html;
            } else {
                console.log("No data available");
            }
        }).catch((error) => {
            console.error(error);
        });
} 
function deleteElement(item){
    remove(ref(db,"Notes/"+item))
    .then(()=>{
        console.log("Data has been removed")
    })
    .catch((err)=>{
        console.log(err);
    })
    window.location.reload()
