python - How to plot a hyperplane in Scatter3D in plotly?

Question

I want to create a stylized graph to explain SVM classifier.

Code and Graph:

import plotly.graph_objs as go 
import numpy as np
import pandas as pd
from plotly.subplots import make_subplots

columns = ['x1','y1','z1','x1','y2','z2','xl1','yl1']
x1 = np.random.normal(1,0.2,50)
y1 = np.random.normal(1,0.2,50)
z1 = np.random.normal(2,0.2,50)
xl1= 50*[2.5]
yl1 =  50*[2.5]


x2 = np.random.normal(2,0.2,50)
y2 = np.random.normal(2,0.2,50)
z2 = np.random.normal(2,0.2,50)

df = pd.DataFrame({'x1' : x1,'y1' : y1,'z1' : z1,
                   'x2' : x2,'y2' : y2,'z2' : z2,
                 'xl1' : xl1,'yl1' : yl1}
                 )

fig = make_subplots(
    rows=2, cols=2,
    specs=[[{"type": "scatter"}, {"type": "scatter3d"}],
           [{"type": "scatter3d"}, {"type": "scatter3d"}]],
)

fig.add_trace(go.Scatter(x=x1, y=y1, mode='markers'),
              row=1, col=1)
fig.add_trace(go.Scatter(x=x2, y=y2, mode='markers'),
              row=1, col=1)
fig.add_trace(go.Scatter(x=[3.5,0], y=[0,2.5], mode='lines'),
              row=1, col=1)

fig.add_trace(go.Scatter3d(x=x1, y=y1,z=z1, mode='markers'),
              row=1, col=2)
fig.add_trace(go.Scatter3d(x=x2, y=y2,z=z2, mode='markers'),
              row=1, col=2)
fig.add_trace(go.Scatter3d(x=[3.5,0,2.1], y=[0,2.5,2.1], z=100*[1,1,1], mode='lines'),
              row=1, col=2)
fig.add_trace(go.Scatter3d(x=x1, y=y1,z=z1, mode='markers'),
              row=2, col=1)
fig.add_trace(go.Scatter3d(x=x2, y=y2,z=z2, mode='markers'),
              row=2, col=1)

fig.add_trace(go.Scatter3d(x=x1, y=y1,z=z1, mode='markers'),
              row=2, col=2)

fig.update_layout(height=700, showlegend=False)

fig.show() 

I want to visualize a stylzed hyperplanes for the 4 graphs. In subplot 1 I simply created a line. How can I achieve a hyperlane in the other 3 graphs? (see picture)

I could not find a good example. Any1 knows some smart codes for my purpose?
