### Description Issue gitlab-ce#34102 allows to view HTML artifacts in a browser window instead of download them locally, but it is limited to public projects only. Since most users need this also for private projects, a proper support to that is the scope of this issue. ### Proposal Extend online view of HTML artifacts to private projects, providing proper authentication to rescrict artifacts access. ### Documentation blurb #### Use cases Using GitLab to create test/coverage reports in HTML format, that must be accessible only by authorized users. ### Feature checklist Make sure these are completed before closing the issue, with a link to the relevant commit. - [ ] [Feature assurance](https://about.gitlab.com/handbook/product/#feature-assurance) - [ ] Documentation - [ ] Added to [features.yml](https://gitlab.com/gitlab-com/www-gitlab-com/blob/master/data/features.yml)
