DABL Chat Slack integration: how can I specify the Slack workspace?

When I want to copy messages from the DABL Chat to a Slack channel via the Slack integration, I get prompted for the Slack channel ID. Where can I specify the Slack workspace URL for the channel?

To send a message to a Slack channel, the workspace URL is not needed to configure the outbound integration - the access token and the channel ID are sufficient by themselves. (Note that you do implicitly need to know and have access to the workspace URL to generate an access token and identify the channel ID.)

The Channel ID itself can be discovered by right clicking the channel name in the sidebar and copying a link. The last segment of the resultant URL will be the ID.

It works, thank you!
