Suppress the message <IPython.core.display.Javascript object>

[jay_sin]

Hello friends,
I am using python 3.8 with jupyter notebook; following are the details regarding the version;

     jupyter core     : 4.6.3
     jupyter-notebook : 6.1.1
     qtconsole        : 4.7.5
     ipython          : 7.17.0
     ipykernel        : 5.3.4
     jupyter client   : 6.1.6
     jupyter lab      : 2.2.4
     nbconvert        : 5.6.1
      ipywidgets       : 7.5.1
      nbformat         : 5.0.7
      traitlets        : 4.3.3

Whenever I open a jupyter notebook file(.ipynb) then each cell as the output as well as the following message;

 <IPython.core.display.Javascript object>

Please see screenshot attached.

Interestingly, when I re-run the cell, the message vanish,s but if I close and reopen the file, the message appears again. For reference purpose, hers is the preamble for my notebook;

import nltk

nltk.download("wordnet", quiet=True)
nltk.download("words", quiet=True)
nltk.download("stopwords", quiet=True)
from nltk.corpus import stopwords


import warnings

warnings.filterwarnings("ignore")

import pandas as pd
 import matplotlib.pyplot as plt
import seaborn as sns

%matplotlib inline

import numpy as np

%config InlineBackend.figure_format ='retina'
from wordcloud import WordCloud

plt.style.use("ggplot")



# from IPython.display import display, HTML

Can I kindly get help, on how can the message be suppressed for ever? Advice is appreciated.
