I'm looking to install an older version of the VSCode [jupyter extension](https://marketplace.visualstudio.com/items?itemName=ms-toolsai.jupyter). (The reason is that I'm using a VSCode build from [Code Server](https://github.com/cdr/code-server) which is as of VSCode v1.57.1 - released this summer - and I'd like to install extensions for it). It looks like the [Jupyter Extension version 2021.6.9999](https://github.com/microsoft/vscode-jupyter/blob/2021.6.9999/package.json#L27) is the newest version of the Jupyterhub plugin that supports VSCode version v1.57.1.

However, the marketplace only displays the last 5 extension versions under the "[Version History](https://marketplace.visualstudio.com/items?itemName=ms-toolsai.jupyter&ssr=false#version-history)" section of the landing page. These versions listed are all too new.

I'm able to find the [source code](https://github.com/microsoft/vscode-jupyter/releases/tag/2021.6.9999) for Jupyter version 2021.6.9999 on Github, but the vsix binaries are not there. I'm not sure how to compile it; seems like it'd be a pretty involved process.

Is there an archive of the vsix plugin files going back further than just 5 releases? Those versions were available earlier this year, so it seems like there should be a way to access the older vsix extensions somewhere. Any thoughts is much appreciated.
