Cloudflare Pages Question

Hello Cloudflare Community,

I have a question on using Cloudflare pages. I am trying to use Cloudflare Pages to deploy a react project to the web. I come to the section of the Page builder that says environmental variables (advanced). What is the difference of loading the environmental variables within the pages interfaces vs. just doing a build command and foregoing or just skipping the loading of the variables within the environmental variables section of the pages interface.

Also for cloudflare pages to accept the environmental variables when inputted into the cloudflare pages UI, do I need to do anything special in my react project?

Thank you so much for your time.
