r markdown - R: How to make second level indented bullet points using RMarkdown ioslides?

Question

How do I make second level bullets in RMarkdown from Rstudio?

I tried

* Level1
  + leve2

and it didn't work. It's not exactly clear how to do it from the tutorial. This seems so simple to do in normal RMarkdown.

```{r}
summary(cars)
```


1. Item 1
2. Item 2
    a. Item 2a
    b. Item 2b

Look at the above one, maybe the spacing is the problem
