@code {
    async void OnContentInserted(ContentChangedEventArgs args) {
        // Obtains the inserted content as a text span
        TextSpan textSpan = await args.SubDocument.GetTextSpanAsync(args.Interval);
        // Converts the inserted content to plain text
        string text = textSpan.Text;
        // Removes inserted images and text boxes
        for (int i = text.Length - 1; i >= 0; i--) {
            if (text[i] == '')
                await args.SubDocument.RemoveAsync(args.Interval.Start + i, 1);
        }
    }
}
