Will the Splunk Add-on for Microsoft SQL Server suffice to access logs from SQL server? Should I use Splunk DB Connect as well?

I wish to get only user access logs from SQL Server. Basically, who accesses what database at what time. For this purpose, is the Splunk add on for microsoft sql server enough or DB Connect is also required ? My understanding is that I could be able to get the user access info from AUDIT LOG but I am uncertain about that.
