Since operation using kohsuke Java library

Hi everyone,

I am using org.kohsuke github Java library and I am trying to get record by using some date filter

GHRepository repository …

and able to get record on Repository level, and want to get similar for other entities like PullRequest, Issues, Teams etc.
since() is not available for other entities, and I also tried for GHEvent class but all fields are not available in class for filter.
So, is there any way to get Event, Audit log or record form specific date by using kohsuke Java library.
Any advices on where to look at to fix or debug further ?

Thanks !
