I apologize, but I couldn’t find any specific information about a Chrome extension called “WAIncognito.” It’s possible that the extension you mentioned either does not exist or was released after my knowledge cutoff in September 2021.

If “WAIncognito” is a legitimate Chrome extension, it might be designed to enhance privacy and security while using WhatsApp on the web. However, without further information or details about the extension, it’s challenging to provide a more specific description or features.

To get more accurate information about the “WAIncognito” extension, I recommend checking the Chrome Web Store or conducting a web search using the extension’s name. This will provide you with the most up-to-date information about its features, compatibility, and usage.
