code-cell inside a "special block" in a markdown cell of Jupyter Notebook

I tried to execute a code inside a “special block” in a markdown cell in Jupyter Notebook:

````{tip}
Here is a sentence.
```{code-cell} python3
z = 100
```
Here is another sentence.
````

It generates an error:

WARNING: Unknown directive type "code-cell".

Is it an expected result?

The following worked!

Place the following in a markdown cell:

````{tip}
Here is a sentence.
```python
print("Hello World!")
```
{glue:}`glued_txt`
````

Place the following in a code cell with a tag remove-cell:

from myst_nb import glue
my_variable = "Hello World!"
glue("glued_txt", my_variable)

ahhh right! I missed that part of your explanation, good point 👍

maybe we can add an extra section here: https://jupyterbook.org/content/content-blocks.html#notes-warnings-and-other-admonitions like “how to insert code outputs into your admonition blocks” and show a short example, then cross-link to the glue docs?
