How do install the package in shinylive from github

### What is your question?

Super cool package and idea here. I'm trying to get this to work in a package that is only available on github. When I follow the docs, I get a packagedown page that opens up a shinylive browser, but it's blank, and when I hit the edit button, it can't find the package function when I try to run it. If I add a `library(mylibname)` to the examples, it still doesn't work because it can't find my package in the webR binary repo. Not sure how to get this to work.

```
> Warning in webr::install(pkg_name) :
Requested package mypackagename not found in webR binary repo.
```
