Deno JavaScript Jupyter notebook issue

I have been struggling with getting started with jupyter notebooks which supports javascript. Deno expects

jupyter

jupyter

to be in PATH, whereas I have tried everything, literally whatever I could do but

jupyter

jupyter

is not being in PATH. Mainly i tried:

-

pip install notebook

pip install notebook

- manully added python 3.12's scripts path to env's PATH
- still jupyter not being recognised as command
-

deno jupyter

deno jupyter

gives the following result:

deno jupyter
Warning "deno jupyter" is unstable and might change in the future.
✅ Deno kernel already installed

deno jupyter
Warning "deno jupyter" is unstable and might change in the future.

whatever flag in jupyter command i run, I get the same result.

please help!
