ipython widgets not working

[ghost]

Hey,

i've tryed to make a simple input textbox but its not working.
The error message i receive is

ipywidgets - a Jupyter kernel connection is required to fully display this output.
Text(value='', description='Compound forumla:', placeholder='Type something')

Here is a example of the code i've tried to run. It works very well in the notebook but not in the myst page

import numpy as np
import matplotlib.pyplot as plt
from xraydb import material_mu, xray_delta_beta, coherent_cross_section_elam, incoherent_cross_section_elam, material_mu_components
import matplotlib as mpl
import ipywidgets as widgets

widgets.Text(
    value='',
    placeholder='Type something',
    description='Compound forumla:',
    disabled=False
)

Also, i have defined modify the the .md file as shown in the tutorials:

kernelspec:
      name: ipython3
      display_name: 'Python 3

and in the .yml file as well

jupyter:
      server:
      url: http://localhost:8888/
      token: 3fcf0b....

Could someone gimme a light in this issue?

Thank you very much.
