How to Track New User Actions Day-by-Day in Mixpanel

Hi, I’m trying to break down user journeys day by day in Mixpanel. I want to see what percentage of new users complete certain actions on specific days after signup like one action on Day 1 and a different one on Day 2, both tied to when they signed up. Has anyone set this up? Curious if you used funnels, cohorts, or a “days since signup” property to get this working and what approach worked best.
