Customize the 100ms video conferencing React starter app with custom CSS and new functions

Hello, 100ms makes high-quality video conferencing APIs, and has a starter app in JavaScript and React, please review here: https://github.com/100mslive/100ms-web and please also review deeper dive here: https://www.100ms.live/docs/javascript/v2/guides/javascript-quickstart

I would like to customize this app's UI to have the following:
- Quick-create a new meeting link from a link
- Dark & light UI
- Whitelabel for my company's UI
- Settings to allow our clients to whitelabel the product with their subdomain and logo i.e. XXX.domain.com/meeting-link and their logo in the top corner

Early specs:
- Settings APIs should be written in PHP & MySQL
- Customization settings such as logo/colors, etc. should be stored in MySQL
- List of meeting links. etc. should also be stored in MySQL in addition to the app's own storage method.

I will set up a server to host this app. I will create the server but would require your help to set up the server to serve the application on this server and configure the domain.

This will be a 2 part project

Part 1: Set up the app on a server and provide me with images of the various screens, I will ask our designer to come up with the customizations
Part 2: Customize the app as per the specifications
