How to write condition for Post-Function custom email

[Deleted user]

I am writing post function to send custom email using below condition

post-function only works when JIRA is Project=XYZ AND issue type = Story AND (Epic link = XYZ-691 OR XYZ-1114)

Till now, I have no idea yet except the below two lines.

issue.projectObject.key == 'XYZ'
issue.issueType.name == 'Story'

How to do for OR condition?

This should work -- 

issue.projectObject.key == 'XYZ' &&
  issue.issueType.name == 'Story' && (
    cfValues['Epic Link']?.key == 'XYZ-691' || cfValues['Epic Link']?.key == 'XYZ-1114'
  )

Let me know, if you run into a problem please include the error.
