How to use the @nivo/scatterplot.ScatterPlotDefaultProps.layers function in @nivo/scatterplot

Defines the order of layers, available layers are:
            \`grid\`, \`axes\`, \`points\`, \`markers\`,
            \`mesh\`, \`legends\`.

            You can also use this to insert extra layers
            to the chart.
            
            For \`ScatterPlot\`, the extra layer should be a component
            and will receive current chart context as props.

            If using \`ScatterPlotCanvas\`, the extra layer should be
            a function and will receive canvas context as first argument
            and current chart context object as second.
