In Jira integration 2.0, there's no link or reference to the items created by the integration once you approve them.
A modal notification like you currently use would work at a one-by-one level. If that makes sense.
Even better would be a tab in the Integration Updates screen with the history of items imported and ignored.
I'd like to take this request a step further to include when the Integration itself is established, and include activity against the Import Queue (even if records are "Ignored").
