vscode.dev with a web extension selected via URL

Question

Is there a way to start a vscode.dev session with a extensions pre-selected via URL?

The official Blogpost just states this possibility for color themes and specific extensions. See here https://code.visualstudio.com/blogs/2021/10/20/vscode-dev#_speaking-of-urls

Is it possible to do this with any extension or combination of extensions? I also didn't find anything in the Backlog for that.

AFAIK, in the announcement video on YouTube, I haven't seen anything about it.

But is it a hidden thing then?

No. I see (at least) when using https://vscode.dev/?extensions=esbenp.prettier-vscode (using Prettier as an example) it will not install Prettier.
