React Algolia Refinement List from Array

I have an object with availability days as an array ie.
days: [“Sunday”, “Monday”]
I want to show a refinement list or any other widget that will allow me to have all days of the week as options and user should be able to click on one or multiple and then results containing all options or even one option should show up.
I am very new to algolia. Please in your response share whether i need to do something on dashboard? also how would i code this widget? It’s probably a refinementList extension but i have no clue how to do this. Please help. Thank you
