Not getting autocomplete for OPAC mod's API

I am using `const OPAC_API = Java.loadClass("xaero.pac.common.server.api.OpenPACServerAPI")` to use the OPAC's mod's API by referring to [this JavaDoc](https://thexaero.github.io/open-parties-and-claims/javadoc/index.html). ProbeJS generates the [dump](https://limewire.com/d/SGzJv#dba9oAG4S6) perfectly but when I hover over OPAC_API, it says `any` and does not generate any auto complete
