Troubleshooting Slack Integration: Missing Channel in Dropdown

Happy Holidays everyone 😃 I've faced a problem with the slack integration: I've connected my slack workspace to Clay, and want clay to send notifications to a slack channel but can't find the needed channel in the dropdown (seems like there're all the channels except for the one I need in the dropdown). Can that be because the channel was recently created? I tried refreshing fields in the enrichment column, it didn't help. Also tried manually adding the channel ID and got 0 result. or maybe it's because my channel is private? the error message is in the screenshot
