How can I use ChatGpt as a Desktop App in Windows

How can I use ChatGPT as a desktop app on Windows 11? Not from the browser tool, and shortcut it. Is it still for MacOS specifically?

Also, how to give my ChatGpt ( which i created from browser shortcut) the absolute internet connection priority.

Because it stops,Lags,Stucks,shows Erorr. How to be get rid of that.

I use a high-speed internet connection (100 Mbps), so its frustrating to experience this
