Isolated browser environments for worktrees

I’m trying to use work trees to develop multiple features at a time. But the problem is on our web application, I need different environments for the web browser. So if I have one chat, which is the main chat, its web browser storage and environment is the same as the work tree that I spun up off of it. So I can’t really work on two parallel tasks simultaneously in isolated environments.

To add to this, you wouldn’t even need Worktrees if I could easily spin up isolated environments for a single repo.
