Is it possible to use Zotero with Collabora?

[jaskonius]

I'm trying to enable Zotero plugin for Collabora.

cat /etc/coolwsd/coolwsd.xml yields

<zotero desc="Zotero plugin configuration. For more details about Zotero visit https://www.zotero.org/">
    <enable desc="Enable Zotero plugin." type="bool" default="true">true</enable>
</zotero>

However, I could not yet figure out what else to do? The 'References' tab does not seem to include any citation capabilities.

A quick research on this yields that, at least when integrated within nextcloud, it is required to upload an Zotero API key somewhere in nextcloud. Is there some equivalent for OpenCloud?
