[SOLVED] How to get email of user who send message to bot in Circuit JavaScript SDK?

How to get email of user who send message to bot in Circuit JavaScript SDK?

I'm creating a bot that will receive a messages in Circuit and then send it somewhere else with email of user that printed this message.

As example I use xlator-bot https://github.com/circuit/xlator-bot

this.receiveItem = function receiveItem(item) {
        logger.info('[APP]: receiveItem');

        if (item.type !== 'TEXT' || self.sentByMe(item)) {
            logger.debug('[APP]: skip it is not text or I sent it');
            return;
        }

        if (!item.text || !item.text.content) {
            logger.info('[APP]: skip it does not have text');
            return;
        }

        self.receiveText(htmlToText.fromString(item.text.content))
            .then (function addResponseItem(responseItem){
                logger.info('[APP]: addResponseItem');
                var comment = {
                    convId: item.convId,
                    parentId: (item.parentItemId) ? item.parentItemId : item.itemId,
                    content: responseItem
                };
                return client.addTextItem(item.convId, comment);
            })
            .catch(function(e){
                logger.error('[APP]:', e);
            });
    };

I want to get email of user who send item in this function as string variable. Can anyone suggest how can I do it?
