How can I get access to _CONNECT_IDENTIFIER from within SQLcl JavaScript

I have would like to customize my SQLcl prompt and I call a javascript file from my login.sql I tried this but without success. Variable dbIdentifier contains the string '&_CONNECT_IDENTIFIER' var dbIdentifier = util.executeReturnOneCol("select '&_CONNECT_IDENTIFIER'"); This one works after login: SQL> select '&_CONNECT_IDENTIFIER'; old:select '&_CONNECT_IDENTIFIER' new:select 'jdbc:oracle:thin:@DEMODB_HIGH' 'JDBC:ORACLE:THIN:@DEMODB_HIGH' __________________________________ jdbc:oracle:thin:@DEMODB_HIGH Is there a way to assign the value of CONNECT_IDENTIFIER into a SQLcl JavaScript variable? I would like my prompt to include the string '*DEMODB_HIGH*'. sqlcl.setStmt('set sqlprompt "🙊 @|yellow _USER|@@@|green ' + someStringManipulation(dbIdentifier) + '|@@|yellow >|@ "'); Thank you
