I have an existing plugin and I'm planning to migrate it to React. Therefore, I used this plugin, but I encountered an issue with the UI display when clicking on the options in the 'generate' menu. The code above is my modification based on the plugin/react-editor template. Could you help me identify the problem?

I have uploaded the code here. https://github.com/zicen/react-editor-2

I have the same issue, in the manifest.json i have this command

  "relaunchButtons": [
    {
      "command": "open",
      "name": "Open Rive to Figma"
    }
  ],

and in main.ts this one:
figma.root.setRelaunchData({ open: "Description" });

but when i try to open the plugin from the sidebar, it throws me this error:

Uncaught Error: No UI defined for command 'open'
