How to Integrate GitLab private projects with JIRA (DVCS)

Hello, I have the issue with connecting Jira DVCS accounts. I use a cloud solution for both services (gitlab and jira). And I can see repos in Jira only if I switch them to public visibility in gitlab.

So, I found the cause of this on the man page of subscriptions in gitlab.
I have the bronze subscription but this feature works only with the silver subscription and higher.

Could you please provide a link?
