Are there any Oneworld lounges in SJO, that I can access as an AA Plat?

The OW site indicates one but it is listed as 3rd party. Has anyone had experience with access to this lounge using either Plat privs on INTL Biz privs.

The other one listed is the SJC one being listed for AA since the OW site does not distinguish between SJC and SJO.
