how do you add a proxy?

[Ender-Ghost-Craft]

what url would I add to the proxy settings, its not very clear? the code is
self.__uv$config = {
prefix: '/school/',
bare: '/bare/',
encodeUrl: Ultraviolet.codec.xor.encode,
decodeUrl: Ultraviolet.codec.xor.decode,
handler: '/uv/uv.handler.js',
bundle: '/uv/uv.bundle.js',
config: '/uv/uv.config.js',
sw: '/uv/uv.sw.js',
da: 'a'
};

and the proxy is 69.eightgrade.com/

I cant use the store, even with a proxy, can you please change the link, or add a way to add apps from settings with a code?
