Unfortunately only the plugin that created these can remove them. I can think of a hack to do this but not sure if it would work 100% (I don’t see why it wouldn’t work though):
- Create a new empty plugin
- Set its ID to the ID of the plugin that you used (it’s the number in the plugin community page link)
- Loop through the nodes (e.g. using Figma.root.findAll) and use setRelaunchData | Plugin API to clear the data in the plugin
