Downgrade from Paid to Free Plan - Contentful

My organization needs to move to the Free plan on Contentful. I need to confirm the website will still work within the Free plan's limits, since my site is actively pulling content from Contentfu. It may still depend on that space and API access. I don't do a ton in Contentful, but I just need to downgrade my Contentful plan. I am updating my website locally using VS Code. This job will be conducted through Zoom Chat and testing on my computer. I need advice on where to look and what to do. You will not be given any code/access; it will BE ONLY looking at my ZOOM screen to see where to go and test. You will not be able to download my website. I also need to clean up a couple of items in VS Code. I use VS Code for dev. Its a SMALL website and hardly any API Calls. We are not using any paid features like publishing, roles.
