Once we have linked Jira with Confluence, there will be a new option called Confluence Page, which appears when you select the Link option in the More issue menu, as shown in the following screenshot:

If you know the exact URL of the Confluence page, you can enter it in the Page URL field, or click on the search for a page link and search for the page you want to link to:

Once you have found the page you want, simply click on it, and then click on the Link button. You will see a page similar to the one shown in the following screenshot:

As you can see, the linked pages will be shown under the Issue Links section in the Wiki Page category.
