Creating activities in the CRM via API

Hi,

I’m trying to wrap my head around adding activities to the ‘Emails & Activities’ feature in Monday CRM by using an automation.

Here’s my use case:

• When someone downloads my e-book, I want to show that in the ‘Emails & Activities’ widget of the contact view.

It seems to be the case that when I create an activity from within the view, it gets created in the ‘Activities’ board.
However, when I create an activity from that same Activities board and link it exactly like the one I just created was linked, it doesn’t show up in the ‘Emails & Activities’ view.

Any clue how to add activities in here via automation and/or API?

Ideally I have something like this automation, but then I can trigger it via Make

Thanks in advance!
