Location of helper config flows

Hi, I’m trying to find and copy the config flow for the schedule helper. I want to piggy back off it to create a scheduler with custom values per time block. I can’t seem to find it anywhere no matter what I grep the repo for. Anyone able to tell me?

Right, so I think I’ve finally found how the config flow for schedule works. It’s some Typescript that’s build in to the helpers page. This leads me to another question, is it possible to dynamically load additional Typescript into that page and override or append to const HELPERS: HelperCreators?
