expected result when execute !cd wordpress && frankenphp php-server &

it should run in background because of & then we could execute another command to access wordpress in another tab

import urllib
print("Password/Enpoint IP for localtunnel is:", urllib.request.urlopen('https://ipv4.icanhazip.com').read().decode('utf8').strip("\n") )
!npx localtunnel --port 80

thanks and best regards
