es_graphical_session_id without endpoint security framework

IN endpoint security events related to user login/logout activity (as well in lock/unlock and remote session attach/detach) there is a graphical session identifier which is a 32 bit integer

typedef struct { es_string_token_t username; ** es_graphical_session_id_t graphical_session_id;** } es_event_lw_session_login_t;

Documentation describes it as an opague number

• @brief es_graphical_session_id_t is a session identifier identifying a on-console or off-console graphical session.
• A graphical session exists and can potentially be attached to via Screen Sharing before a user is logged in.
• EndpointSecurity clients should treat the graphical_session_id as an opaque identifier and not assign
• special meaning to it beyond correlating events pertaining to the same graphical session. Not to be confused with the audit session ID.

*/ typedef uint32_t es_graphical_session_id_t;

Question: is there a way to get this graphical session identifier outside of endpoint security framework, for ex. from process id or audit token? Is there an API for that?
