Is it possible to pre-install packages in a shinylive for R app, instead of installing them with webr::install at runtime?
(In my opionion, this has some advantages: It causes less requests to other sites, so less possibility to cause issues with cross-origin policies. And as soon as the R session is started, the packages are available, the downloaded size may be larger, but the potentially slow installation step is not necessary.)
According to this answer to as similar question it should be possible by just extracting the packages downloaded from the webR binary repo to the R library on the rwasm vfs.

I was not able to get this to work. This might be due to other issues with the app or xhr request being blocked. So I post this here in the hope it helps someone.
Edit: It is planned to include this in the export functionality of shinylive, as mentioned in this feature request.
