Hi, I am having the same problem as above. I also confirmed I am not currently logged into any Slack Workspaces and there are no pop-up blockers.

I am running Tokyo Patch 4a

Version 4.1.0 for the "Conversational Integration with Slack" plugin

In the Log table, I see Error "Can't find External App Information: no thrown error" and "Exception Got while fetching the information from proxy DC Instance: no thrown error"
