What is the difference between CURRENT_IS_ROLE_ENABLED and SESSION_IS_ROLE_ENABLED

In Oracle 19c the DBMS_SESSION package state this:

IS_ROLE_ENABLED Function

This function determines if the named role is enabled for this session.

Note:

This function is deprecated starting in Oracle Database 19c. Use DBMS_SESSION.CURRENT_IS_ROLE_ENABLED or DBMS_SESSION.SESSION_IS_ROLE_ENABLED instead.

What are the differences between these two functions? When to use which one? The documentation does not really help here:

SESSION_IS_ROLE_ENABLED: This function determines if the named role is enabled for the login user session

CURRENT_IS_ROLE_ENABLED: This function determines if the named role is currently enabled.
