Security considerations:
-----------
1) OpenAI api key handled via extension-scoped chrome.storage.local apis and used only within "Authorization" header to sign OpenAI API requests (which is not exposed or tracked, even if "webRequest" API enabled in some other malicious extension)
2) OpenAI requests goes through official OpenAI NPM-package and running only within background service-worker which helps with XSS-kind of attacks.
3) Don't enter or share your OpenAI key anywhere else except extension's settings page (options page)
