Hi,
I have a simple map with a callback and I want to relocate when the button is clicked.

 dbc.Button(
        "xxx", id="dum", className="mb-2", style={"width": "100%"}
    )

html.Div(
        children=[
            dl.Map(
                children=[
                    tile_layer,
                    dl.LayerGroup(id='dynamic-layers')
                ],
                zoom=17,
                zoomDelta=0.1,
                center=[53.839741676507415, 8.76634112590542], 
                style={
                    "width": "100%",
                    "height": "100%",
                    "display": "block",
                    "background": "black",
                },
                id="fps-map",
            )
        ],
        className="map-div",
        style={"flex": "1"},
    )


@app.callback(
        Output("fps-map", "center"),
        [Input("dum", "n_clicks")],
)
def update_map_center(n_clicks):
    ctx = dash.callback_context
    no_update = dash.no_update
    if not ctx.triggered:
        return [], no_update
    return [49.080249309032915,16.35538617966371]
