How do i setup websocket on GCP Flex environment?

Question

I am using laravel 6 and I want to deploy laravel based websocket server using supervisor on google cloud Flex app engine platform.

I am using this package: beyondcode/laravel-websockets

I have setup everything and everything is working fine on local machine! What is the exact procedure to follow to deploy it on GCP?

My additional-supervisord.conf

[program:websockets]
command = php %(ENV_APP_DIR)s/artisan websockets:serve
enviroment = PORT="6001"
stdout_logfile = /dev/stdout
stdout_logfile_maxbytes=0
stderr_logfile = /dev/stderr
stderr_logfile_maxbytes=0
user = root
autostart = true
autorestart = true
priority = 10
stopwaitsecs = 20

App.yaml

runtime: php
env: flex

runtime_config:
  document_root: public

service: orders

skip_files:
  - .env

#only for testing purpose. 
manual_scaling:

You can find in the official documentation how to use WebSockets to create a persistent connection from a client (such as a mobile device or a computer) to an App Engine instance.

Please consider that WebSockets connection will time out after one hour.
