Is there a way to Find Jira tickets which have Zephyr test cases coverage under them via JIRA?

[Jaspreet Kooner]

I have a project  where some bugs have a test cases under them and some not - I need a way to show a KPI how many tickets under this project have test case coverage now?

These are bugs under a BAU JIRA  project across multiple products  under this BAA project- so i cannot use Zephyr test cycles/plans etc .

I need main JIRA filters to  generate a list/chart etc. for me.
