Allow user to retrieve issues based on Service Desk request Channel

In the view issue page, there is a section of Service Desk Request that shows the information of Request type, Customer status, and Channel. Currently it's not possible to retrieve list of issues based on Channel in issue navigator using JQL.

It'll be great to be able to search issues based on Channel to differentiate issues created from JIRA or customer portal.
Attachment below

In the database, the following query only lists down the issues created from "Portal"

SELECT * FROM entity_property WHERE PROPERTY_KEY='request.channel.type';
