How to link GitHub repository with JIRA project?

Question

I have a software project in JIRA and want to link that project with a GitHub repository so that when I create tasks in the JIRA project I can branch out in the corresponding GitHub repository, etc. I was able to link my GitHub account with my JIRA account (https://confluence.atlassian.com/adminjiracloud/connect-jira-cloud-to-github-814188429.html) but I don't know how to connect one of my JIRA projects with a specific GitHub repository.

For example, when I create a task in my JIRA project I expect to see a link on the task page to create a branch. There's no such links because the project is not linked to a repository.

EDIT: I don't see the Development panel on the issue page in JIRA. If I were able to see that panel that would solve this problem (likely).

EDIT: I am trying to see this panel on the issue page. This is from JIRA's help pages.

EDIT: Instead I see this (notice no Development panel on the right side that allows me to create a branch)
