I wanted to ask for any library for showing off full screen loaders, I am already using react-hot-toast for showing toast messages, but I wanted a Loader to take on full screen with a little opacity in the background when the APIs are being called, I am very new to Next, and I just wanted to implement the APIs on the front-end, I see that there is already a cool loader, I tried searching through the project, but didn't found it, I guess, next js provides it by default, I dunno, please tell help me with a library for a cool loader like, more of a professional loader for a front-end of medical laboratory dashboard style
