Is the conventional-commit specifications for commit bodies not supported or am I using it wrong?

Making a commit like this:

```
fix: this is a test commit

Here we add some more context.

According to the conventional-commit specs this should appear in the changelog/release-notes.
````

Unfortunately the commit body will not show up 😔 (from what I can see the same goes for commit footers)

Is this my fault on misunderstanding how it is supposed to work, or does release-please simply not support this?

My setup is a github action release-please workflow for a node project
