I’ve tried creating a new header hero but I’m so lost what to do. The documentation doesn’t help since there’s no button example. I can easily place a text/image on the header element but I have no clue how to merge a button on.
You don’t actually add the text or button in the page hero.
What I’m suggesting is to create the whole thing (image, text and buttons) using GenerateBlocks. This is what I’ve done for Target: https://gpsites.co/target/
