   source .venv/bin/activate # for bash/zsh
   source .venv/bin/activate.fish # for fish
   source .venv/bin/activate.csh # for csh

   Note the HTTPS URL you get.

2. Update your Slack app's request URLs:

   • Go to your Slack app's settings.
   • In "Event Subscriptions" and "Interactivity & Shortcuts", update the request URL to your HTTPS URL followed by /slack/events.
   • In "OAuth & Permissions", update Redirect URLs to your HTTPS URL followed by /slack/oauth_redirect.

3. Start the application:

   app
   

Your Slack app should now be running and connected to your Slack workspace! If you're adding commands, your commands in development will be prefixed with /dev-COMMAND. When deploying your app, you must set the ENVIRONMENT env var to production.
