Have you ever deleted a post online or made a profile private and wanted it to be removed from search results? If that content is no longer available to the public, it should eventually be removed from search results but, if you want to expedite it, you can actually submit a request directly to Google to have it be removed from search results by using this tool (https://search.google.com/search-console/remove-outdated-content).
This tool only applies if the content is no longer publicly available so make sure to have it taken before submitting a request.
If you want to learn more about the tool you can read about it here (https://support.google.com/webmasters/answer/7041154).
