[NEED HELP] How to create these "Buttons" in illustrator?


Hey Guys,
hey guys, I'm new to this community and I have the first question right away:
I'm creating watchface content.
I'm trying to figure out how do I create these "buttons" can somebody tell me if this is a single element or is it created from more elements?
First thoughts I had was, creating the Kontur for the gradient as a single element and the black background as well, then group them together, because the pathfinder won't work with that. Everytime I use it the gradient won't work like I want them 🙊
It drives me crazy 🙊
Any help or workaround is appreciated 😊
Thanks in advance
