How to refresh backend service metadata and annotation files in VSCode Fiori Tools?

Hi,

When generating a fiori elements app with fiori tools in VSCode the project is built based on the backend service metadata and annotations xml. Super.

But what if I want to change the UI annotations? Should I edit the xml in VSCode, or the CDS in the backend?

If I change CDS annotations, is there a way to "reload" the changes into my existing VSCode project or do I need to regenerate the app from scratch?

Thanks,

T
