Linking Jira requirements to Test cases in Zephyr Squad

Hi Team,

My organisation implemented Zephyr Squad for Testing. I am struggling to link Jira requirements to test cases in Zephyr Squad though I found out Traceability Matrix (Forward / backward) option available. 

My objective is to link existing test cases in Zephyr Squad to Jira requirements and would like to add the test summary back in Jiran dashboard. Any suggestions would be really appreciated.
