Issue:
You accidentally published private artifacts to a public install page.
Possible Solutions:
To disable and remove an already created public install page of an artifact, you can use the build-artifact PATCH endpoint of the Bitrise API. You will still be able to view it from your Build's Artifacts page and re-enable it in the future. For more details, you can read our guide on Disabling the public install page of an artifact.
You can permanently remove a published artifact with the build-artifact DELETE endpoint of the Bitrise API.
