Get code view of configured Items

Is there some way to see the textual equivalent of Items configured via UI in OH3? This would be helpful to configure on Item completely by hand and than copy pasting that for bulk creation.

Yes, but only via the API Explorer in the Developer options. There’s no ‘Code’ button to give you a nice YAML like there is for Things (only for the Item metadata, but not the Item itself)

Where in the Rest API is that?
