FSE Frontpage

FSE is confusing me a litte bit about the Frontpage / Homepage. Ok, I created a page called "Home", used the "frontpage"-tepmplate and mad it as a static homepage. But where do I now work? It seems that I have to change things in the frontpage-template and not in the Page called "home".  Is this right? Because I didn't found anything in the web and your video also says nothing about it. For the other pages and posts it is clear that I#m not working in the template, but the frontpage seems to be special. Or is this wrong and I have to empty the frontpage template and work in the page called "home"?
