how to bind multiple ports to share before running the main script like Ngrok?

[krigeta]

I am trying to bind 3 ports using this approach:

command = 'source /kaggle/tmp/.venv/bin/activate; python app.py'
port = '6969'
port_t = '8077'
port_f = '9876'
# ------------------------
os.system(f"filebrowser -r /kaggle -p 9876 > /dev/null 2>&1 &")
%load_ext tensorboard
%tensorboard --logdir logs --port 8077
cmd = f'/kaggle/working/zrok/zrok share public http://localhost:{port} --headless & /kaggle/working/zrok/zrok share public http://localhost:{port_t} --headless & /kaggle/working/zrok/zrok share public http://localhost:{port_f} --headless & {command}'
get_ipython().system(cmd)

but I want to achieve something like this but using Zrok and not Ngrok:

import os
from pyngrok import ngrok
from IPython.display import clear_output, Javascript
ngrok.kill()
%cd /kaggle/working/program_ml
os.system(f"filebrowser -r /kaggle -p 9876 > /dev/null 2>&1 &")
clear_output()
%load_ext tensorboard
%tensorboard --logdir logs --port 8077
p_tunnel = ngrok.connect(6969)
t_tunnel = ngrok.connect(8077)
f_tunnel = ngrok.connect(9876)
clear_output()
print("Applio Url:", p_tunnel.public_url)
print("Tensorboard Url:", t_tunnel.public_url)
print("File Url:", f_tunnel.public_url)
print("Save the link for later, this will take a while...")

!source /kaggle/tmp/.venv/bin/activate; python app.py
