Troubleshooting Lindy Gmail to Slack Integration Errors

I have built a simple Lindy to scan my Gmail for certain labels, then most a summarized version of the email into a certain chat channel in Slack. I’ve set up the triggers and Slack nodes. Each channel in Slack is a private channel, and I have added the Lindy app to each private channel. However, I get an error of “No Slack channel found with the name of [channel-name]” and “The Slack channel [channel-name] does not exist. Please check the channel configuration and ensure the channel name is correct before trying again.” Please help.
