Filtration in Jira by the criterion of integration with TestOps

I am using integration TestOps with Jira. Now our team needs visually see tasks in Jira that are not integrated with cases in TestOps. I think that it possible with filtering by criterion availability of integration in Jira, but I can’t write request via JQL which uses fields Linked Test Cases (screen). Maybe someone faced a similar task? Need any solution1
