With blocks you can add anything you would like, including a podcast episode.
Here you saw that a Podcast can be added via the Audio block.
For the rest you can find any block you would like. Below an example of a Header and a Paragraph.
A standard heading
A paragraph where you can use long text, white spaces, etc.
Simple and intuitive. 🙂
There you can create some extra space with a spacer.
And further Blocks to be found by clicking on Browse All.
