[Python] Plot convex-hull in 3D using plotly

I am trying to use plotly to plot the 3D convex-hull of a set of points. I am using Mesh3d objects but the surfaces are not created correctly (see the picture below). How can I fix this?

import plotly.graph_objects as go
import itertools, math, numpy as np

from scipy.spatial import ConvexHull

# this simply creates a set of points
n = 3
m = 3
E = np.array(list(itertools.product(np.arange(-1, 1.1, .5), repeat=m)))
V = [
[-2.20676418, 1.53670924, -1.5541674 ],
[ 0.63437404, 0.07306301, 3.82253086],
[ 3.19989112, 0.71987311, 2.79373418]
]
x = np.array([np.dot(V, e) for e in E])

# then I compute the convex hull using scipy
xc = x[ConvexHull(x).vertices]

fig = go.Figure()
fig.add_trace(go.Mesh3d(x=xc[:, 0], y=xc[:, 1], z=xc[:, 2], color="blue", opacity=.5))
fig


Current output is:
