How to select Zotero libraries using zotlit

What I’m trying to do

I’ve been experimenting with the zotlit plugin, but so far it seems to only find citations that are in the “my library” library in Zotero. Most of my citations are actually in another library, which is a group library. I’m trying to let zotlib use this library, or ideally all my libraries, like Zotero does, but can’t find any way to select libraries in the zotlit settings.
Things I have tried

Zotlit lets you select the location of the Zotero database, which does seem to be correct in my case (it does find citations in “my library”), but I don’t see any method to select libraries. The zotlit documentation also does not mention it.
