Dash shownotification

Dash Python

Is there a convenient way for me to send error messages directly to the page.

My idea is as convenient as shiny shownotification.

example ide app

@callback(
    Output('graph-content', 'figure'),
    Input('dropdown-selection', 'value')
)
def update_graph(value):
    if value is None:
        shownotification("error message",type = "error",position = "top-right")
        raise PreventUpdate
