# For this to work correctly you need to create a webhook. You'll also
# need a GSuite account (there are free trials if you don't have one)
#
# - Open Google Chat in your browser:
# Link: https://chat.google.com/
# - Go to the room to which you want to add a bot.
# - From the room menu at the top of the page, select Manage webhooks.
# - Provide it a name and optional avatar and click SAVE
# - Copy the URL listed next to your new webhook in the Webhook URL column.
# - Click outside the dialog box to close.
#
# When you've completed, you'll get a URL that looks a little like this:
# https://chat.googleapis.com/v1/spaces/AAAAk6lGXyM/\
# messages?key=AIzaSyDdI0hCZtE6vySjMm-WEfRq3CPzqKqqsHI&\
# token=O7b1nyri_waOpLMSzbFILAGRzgtQofPW71fEEXKcyFk%3D
#
# Simplified, it looks like this:
# https://chat.googleapis.com/v1/spaces/WORKSPACE/messages?\
# key=WEBHOOK_KEY&token=WEBHOOK_TOKEN
#
# This plugin will simply work using the url of:
# gchat://WORKSPACE/WEBHOOK_KEY/WEBHOOK_TOKEN
#
