I downloaded the course but still I can't find how to edit content

Hi, I am a noob as WordPress web developer. I have received the course and saw it, still, even though I understand how to properly create blocks within a section of the home page (I am using a one page site for now, similar to the demo version), I can’t find the way to edit the contents, in example:

In the section “Our Services” I want to change the logos of the 3 services, and the name and description (latin) of each service.

Can someone pardon my noobiness and direct me where to look for this in WordPress Admin?

Thanks in advance.

Never mind, I found it now.
