When i upload more thant 4 i got this error in the console but i would like to intercept and show it on screen.

How can i do that?

You can reproduce with the demo site https://www.fluentui-blazor.net/InputFile

I thougth i could use OnFileError but it's not working for now.

OnFileError="@ErrorAttachmentHandling" OnCompleted="@OnAttachmentCompletedAsync"
