How to approach the development of a web browser based on Chromium?

Question

Chromium

Hello!

The task is to make a web browser on an existing engine with the ability to replace unique identifiers and support multisessions.

Could you indicate the direction in which to move? What to take as a basis, which libraries / projects are worth paying attention to.

I thought to take chromium and do everything through plugins or, at worst, take an electron and use webview.

Tell me please.
