  • Hi Devs, I coded a Lightning Message Service channel in VS Code, Deployed to Org, & then due to some issues later deleted from Project AND Org. But I think the LMS is STILL in the Org coz after cleaning up, it no longer allows me to Deploy to Org, and results in an error.

    Do you know Where & How in Setup to: a) find Lightning Message Service channels, and b) completely delete them from the Org?
