Has anyone used the Perfect Abstractions Office module to read .xlsb files or has a sample code of how to use it?

I have been able to read .xlsx files with the ‘xssf.usermodel’ package and ‘XSSFWorkbook’ class, however, I am struggling with the .xlsb files, which I believe should be read with the 'xssf.eventusermodel ’ package and ‘XSSFBReader’ class.

Thanks.
