Does Slack beta require you to have Slack open/logged in

[GenDemo]

Hi everyone
Recently I started to get scheduling errors for Looker Dashboards

Error: An error occurred for action looker-integration://1::slack_app. The action could not be executed.

Could this be because my slack is not open?
When I click on the “your content” link in the email, then the dashboard opens and I can’t see an issue.
