Is it possible to upload files using a menu item instead of a button?

There is public Upload() method that can be executed from anywhere you need:

radzenhq/radzen-blazor/blob/master/Radzen.Blazor/RadzenUpload.razor.cs#L164


      
          /// <summary>
          /// Gets or sets the child content.
          /// </summary>
          /// <value>The child content.</value>
          [Parameter]
          public RenderFragment ChildContent { get; set; }
          
          /// <summary>
          /// Uploads this instance selected files.
          /// </summary>
          public async Task Upload()
          {
              await JSRuntime.InvokeAsync<string>("Radzen.upload", fileUpload, Url, Multiple, false, ParameterName);
          }
          
          readonly IDictionary<string, string> headers = new Dictionary<string, string>();
          
          internal void AddHeader(string name, string value)
          {
              if (name != null)
              {

I'm confused. need to create an instance of the RadzenUpload class and call its Upload? I'm trying and getting an Error: System.ArgumentNullException: Value cannot be null. (Parameter 'jsRuntime')

It will be been if you check our demos. You cannot upload anything without having RadzenUpload to pick your files.
