but I don't know how to do it with openlibrary

OL625575W

i tried write: openlibrary:OL625575W or openlibraryorg:OL625575W
but not works

calibre, version 8.16.2

I don't use OpenLibrary, and from what I've seen of the default Calibre plugin, it doesn't collect much data. I've created a plugin, which I won't be supporting in case any information on the OpenLibrary website changes. The only requirement is that it uses the identifier openlibrary:OL25898225M to collect the data. I hope you find it useful. Add it as a metadata download plugin.

I tried deleting the database plugin, I also disabled all other plugins but it still gives me the same error.
