I have questions regarding trailer Hub Greasing ?

Trailer is new to me, and I want to grease the 'hubs', and want some instructions.

I've included a pic of the Hub. Inside the hub is a rubber boot, and I assume there is some type of Zerk fitting (but not sure) where I can attach my grease gun ?

Has anyone seen this type of Hub before, and how do I go about adding grease ?

Thanks !
