I still lack experience in programming; much of the code I've used as a basis is derived from existing sources (GoogleSearch). If the pull request is deemed relevant and useful for implementation in LibreChat, I'd appreciate assistance in rectifying these errors. 😅

This tool would be really great. Bing Web Search has a free tier which would work well for many users.

I am not the reviewer, just an external interested party, and have left a single comment (so far).

I have also briefly looked into your failing unit test, but can't see why it's failing with toolFunctions[testPluginKey] not being a function. Looks like it should be there, plus it's analogous to the GoogleSearch tool test.

I hope @danny-avila can take a look?
