I commented a Github PR link (which is part of an organization - private repo) in a Jira ticket, but instead of getting the PR information, Im seeing the following error message:

In the other hand, if I put a PR link from a public repo, the PR information is displayed correctly.

Im using this in a Jira Cloud instance. I have the feeling is related to the fact I havent setup DVCS connector (or something else is missing there). However, I havent been able to find the link to DVCS connector in jira cloud.
I followed what is mentioned in this link: https://confluence.atlassian.com/adminjiracloud/connect-jira-cloud-to-github-814188429.html However, there's no "Integration" section in my jira instance (from step 2.4). Could it be that part was moved to another section?
Thanks in advance!
