Zotero find available PDF

Zotero is a great tool for literature managements.

To be more convenient, the option Find Available PDF can be used to automatically retrieve PDF either from OA Copies, i.g., from Unpaywall, or customized resolvers, like paid proxy..

Here is a way to custom PDF resolves: Preferences -> Advance -> Config Editor, find the setting: extensions.zotero.findPDFs.resolvers, then add JSON array of objects.
