What do you think about this, @lkuligin ?

[lkuligin]

I think that's an amazing integrations, thanks for working on it!
I owe you a review, I'll try to do it over the weekend and I'm sorry for the delay.

[jorge-jrzz]

No problem @lkuligin, I'm on standby for any changes or questions about the code 🫡

[lkuligin]

@jorge-jrzz I'm sorry for the delay. I approved but there a few minor comments. It would be great if you could take a look.
Thanks again for the great contribution!

Hi @lkuligin, don't worry, I already attended and answered the comments you made, and as I mentioned in the last one, it would be great if it could be downloaded like the Gmail toolkit, something like this:

pip install -qU langchain-google-community[calendar]

Anyway, I'll keep an eye out for anything.
