The 'Send Message to Channel with Slack' integration allows you to send messages to Slack channels directly from Clay. However, it doesn't control notification sounds, which are managed by Slack's settings. To troubleshoot this issue:
1. Check your Slack notification settings for the specific channel.
2. Ensure the bot sending the message has the correct permissions.
3. Verify if the issue occurs for all messages or just those sent via Clay.
If the problem persists, you may need to review your Slack app's configuration. For further assistance, please request to talk to a person who can provide more detailed troubleshooting steps.
