Need to know about working of Pixel Streaming Infrastructure

I recently started working with Pixel streaming and this is my first time interaction with UE too. So, as of now all i have done is created a default third person project in unreal engine and added pixel streaming plugin(as per the documentary) and all i am able to understand how to run that on my browser with the help of SignallingWebServer in Pixel streaming Infrastructure repo and able to run the frontend implementation that Epic games provided for frontend. As they have provided 2 implementations ie, Epic games and react, i am able to run react on local host. but cant understand what to do after that.

After this i am unable to understand how to use ui-library and library in my project and work on frontend part. I read the github repo of Pixel streaming Infrastructure but it is going bit above my head, I am able to understand how different components of frontend works. but i want to actually work how to use all of the files like SFU, matchmaker, etc in my frontend and make UI for the pixel streaming, just need some guidance how to start working with it and what should i implement in my react that is provided in the Pixel streaming Infrastructure. I hope you understand my struggle with this.

Can I suggest you something else? Check out Arcware’s CloudRT streaming platform. Arcware made their servers, especially for streaming Unreal Engine Applications. You don’t need to make any signaling server of your own. You can pack your project and upload it to their server. And it will work.
Now front end part, check out their live streaming demos here: Showcase | Arcware , they all have a “stream now” button; it’s fully responsive and with a complete front end.
You can also check out their documentation for details on how to use their SDK to integrate the front end with streaming. They support any JS base platform, like React, VUE, etc.
