List issues assigned to the authenticated user across all visible repositories including owned repositories, member
repositories, and organization repositories. You can use the filter query parameter to fetch issues that are not
necessarily assigned to you.

Note: GitHub's REST API considers every pull request an issue, but not every issue is a pull request. For this
reason, "Issues" endpoints may return both issues and pull requests in the response. You can identify pull requests by
the pull_request key. Be aware that the id of a pull request returned from "Issues" endpoints will be an issue id. To find out the pull
request id, use the "List pull requests" endpoint.
