I am trying to create a source editor extension in Xcode 16, I just created a blank macOS project and added an extension target. I also changed "XcodeKit.framework" to Embed and sign, but when I run the extension on my Mac, I can't see the command under "Editor" menu. I even tried to clone a sample extension from online and run it, even in this project I'm unable to see the commands under "Editor" menu. Has anyone faced this issue?
