SLack in Dashlet

Hello all!
Im trying to connect my slack account in the web dashlet on the main screen i’m getting this error

test-rr02784.slack.com refused to connect.”

Any ideas?

Hi,
Are you only going to add the URL of Slack in a Dashlet?
How are you going to attach slack with a Dashlet?

Thanks for the quick response. I was hoping to have the actual chats in the dashlet.
What i’m really looking for a chat for team collaboration within CRM

Thanks.
