Slackbot that posts new emoji added to your workspace into a channel.
Deployment
I deploy this as a lambda function behind an api gateway. You should also be able to run this as a standalone webserver.
Config is set via either environment variables or with ssm parameter store. If you use ssm parameter store set enviornment variable SSM_PATH to the prefix where these values will be set.
App configuration in slack
To run create a new app on your workspace:
Get Basic Information > App Credentials > Signing Secret. This is your SLACK_SIGNING_SECRET
