Google Feeling Lucky auto-redirect !lucky

DuckDuckGo !Bangs offer the following shortcuts for Google's Feeling Lucky (going straight to the first result) search option:

Unfortunately, they don't work anymore due to redirect notices that get shown. This service enables you to skip redirect notice by altering your search from the original query e.g.:
https://www.google.com/search?q=site:developer.mozilla.org+Object.hasOwn&btnI

To the modified one made against this val's HTTP endpoint:
https://vladimyr-googlefeelinglucky.web.val.run/?q=site:developer.mozilla.org+Object.hasOwn

Additionally, you can define custom search shortcut inside your browser to allow a local bang-like experience:
