Repeater inline delete action

Hello, I'm trying to make the repeater delete action inline. Since having the entire header for one icon takes up quite a bit of space, and my client has specifically asked for this. Yet I just can't figure out how to do it, I've tried a custom action in the schema. But there I can't figure out how to access the repeater values, I hope someone has an idea how this would maybe work. Thanks in advance!
