How to use /assets/shared-bundle.js? should I?

I am using https://github.com/evoko/zendesk-theme and it has /assets/shared-bundle.js with interesting variables like colors. Found nothing about it in manual. Is it for zendesk use only or it is also can be used in my theme building? 

const PALETTE = {
black: '#000',
white: '#fff',
product: {
support: '#00a656',
message: '#37b8af',
explore: '#30aabc',
gather: '#f6c8be',
guide: '#eb4962',
connect: '#ff6224',
chat: '#f79a3e',
talk: '#efc93d',
sell: '#c38f00'
}}
