Display post category name within loop in custom theme (automated newsletter)

[moltocomuni]

hi,
I bought your plugin and find it awesome
I'm trying to display a list of posts in this way:

Articles (wordpress native posts)

Title article 1
category
excerpt

Title article 2
category
excerpt

....

News (custom post type)

Title article 1
Title article 2
...

I can't find the way to split the 2 lists and display the category name
I read the guide (https://www.thenewsletterplugin.com/documentation/newsletter-themes) but it's not clear to me how to code it.
My starting theme is default (found in newsletter-automated folder)

can you please help me?
thanks
MC
