JIRA issue information in Confluence by anonymous access JIRA

[Deleted user]

In JIRA Sofware we have allowed anonymous access to our projects.
On a Confluence-page we have links to JIRA-Issues. But in Confluence is not showing the headline of the issue.  There is a warning that the user is not allowed. When the user clicks on the issue he can watch the issue in JIRA.
What must I do to see the Information (headline etc.) from JIRA in Confluence by a user that is a confluence-user and not a JIRA User?

You need to enable anonymous access to the issues so the non-JIRA user can see the data on the issue.

What setting do I apply for that?
I already add the Anyone group to the Browse Project permission in the permission scheme for the project.
