How to filter or get list of all the initiative which has Epics linked from specific project?

[Chella Perumal Thirumalainambi]

I want to see only the initiative/capability which has epics linked(as parent) from a specific project.

My project name - [CN - Core Networks]

So all my epics starts with CN-XX, CN-XX

There are more than 500 Initiative/capability in JIRA we use, but my epics will be linked only to some of the initiative/capability lets say 50 initiatives. Now I want to list or filter only those initiatives which is tagged as Parent link for the epics created under our project.
