I could not find what I was looking for

Hi! I have a documentation issue on Angular-InstantSearch, I could not find what I was looking for which is:

Most of the documentation for v4 is missing on how to extend UI widget like https://www.algolia.com/doc/api-reference/widgets/refinement-list/angular/#connector

Hi @apijay, the documentation is still for v3, but it should be largely the same. You can however the custom widgets in the storybook for an example: https://github.com/algolia/angular-instantsearch/blob/v4/examples/storybook/src/custom-widgets.ts
