I need to generate a Python code using plolty library where i need to create secondary x-axis (without creating primary x-axis) with primary y-axis. Could anybody give suggestiions: I tried to put side=’top’. it does not work.

fig = go.Figure()

  # Add traces to the figure (primary x-axis and primary y-axis)
  fig.add_trace(go.Scatter(x=x, y=y1, mode='lines', name='Sin', line=dict(color='blue')))
  fig.add_trace(go.Scatter(x=x, y=y2, mode='lines', name='Cos', line=dict(color='red')))

  # Add secondary x-axis (xaxis2)
  fig.update_layout(
    xaxis2=dict(
        title='Secondary X-axis', 
        overlaying='x',           
        side='top',              
        showgrid=False,           
        zeroline=False 
      )
