bookdown extensions in rmarkdown notebook

Question

I would like to use some of the bookdown extensions while using html_notebook as my output format. E.g. this works:

---
output: bookdown::html_document2
---

```{theorem}
My proof here.
\```

knitr::knit("test.rmd", "test.html")

but this does not:

---
output: html_notebook
---

```{theorem}
My proof here.
\```

knitr::knit("test.rmd", "test.html")

Is there a way to use these extensions in rmarkdown notebooks?
