Use Google Colab Resources on local IDE

I have a big doubt. I see a lot of blog posts where they say that you can use the Colab front-end to edit a local Jupiter Notebook

However, I don't see the point. the actual advantage would be to use something like DataSpell or some local IDE, on a remote Notebook on Colab, and use the Colab Resources to do the computations, so you have:

1. IDE level of suggestions (Colab is pretty slow compared to local IDE)
2. cloud computing performances and advantages

However, I don't see any blog talking about this. Is there any way to do this?
