'fill' under the curve after a certain x intercept?

I have created a graph using: plotly.figure_factory.create_distplot
does anybody know how to fill below the curve after a certain x-intercept? (see below)

Thank you in advance

I want to fill/highlight under the curve after the median
Code:

import numpy as np
import pandas as pd
import plotly.offline as pyo
import plotly.figure_factory as ff
import plotly.graph_objects as go

np.random.seed(42)
hist_data = np.random.normal(0, 1, size=(1, 200))
MEDIAN = np.median(hist_data)
MEDIAN_r = np.round(MEDIAN,2)

group_labels = [‘dist’]

fig = ff.create_distplot(hist_data,
group_labels,
show_hist=False)

fig.update_layout(showlegend=False,
template=‘plotly_white’,
#fill=[dict()]),
shapes=[ # Line Diagonal
dict(
type=“line”,
yref=‘y1’,
y0=0,
y1=0.5,
xref=‘x1’,
x0=MEDIAN,
x1=MEDIAN,
line=dict(
color=“gray”,
width=4,
dash=“dot”,)
)],
annotations=[
go.layout.Annotation(
text=‘Median: ’ + str(MEDIAN_r),
align=‘left’,
showarrow=False,
xref=‘x1’,
yref=‘y1’,
x=.15,
y=.5,
# bordercolor=’’,
# borderwidth=5
font_size = 15)]
)

fig.update_xaxes(title=‘Zij’)
fig.update_yaxes(title=‘Density’)

pyo.plot(fig, filename=‘Zij_distplot.html’)
