Hi @Wasif ,

(function() {
    var existingTranslationsArr = [];
    var grTrans = new GlideRecord('sys_user');
    grTrans.addActiveQuery(); // Filter by active users.
    grTrans.orderByDesc('created'); 
    grTrans.setLimit(10);
    grTrans.query();
    while (grTrans.next()) {
        existingTranslationsArr.push(grTrans.getValue('sys_id'));
    }
    var recipientList = existingTranslationsArr.join(',');
    gs.info('Recipient List: ' + recipientList);
    return recipientList;
})();

Use above script to return list of sys_id.
Please mark it as accepted solution and helpful if it works for you.

Thanks,

Anand
