I downloaded metabase jar file on my desktop and running the application.
In my slack workplace I configured a new bot called nbot and generated a new API token in the integration settings.
In metabase I went to the ADMIN panel and also pasted this token under Slack settings.
I created a new channel metabase files and added nbot to that channel.
I see the bot in my slack workspace but it shows up as inactive (grey) and does not respond to any commands.
