I would absolutely recommend discussing a wide variety of relevant skills and achievements during interviews, and that could very well include activities such as this. Early on in your career, you may not have a great deal of work history to substantiate your talents, so the more you can draw on transferable skills and experiences to show that you are a fantastic candidate, the better.
While this does not appear to be a formal engagement (a paid position, or unpaid work aligned with an official organization) I would encourage you to include this on a resume in a section such as “Notable Achievements.” I would then carefully describe the goals you established, the kinds of responsibilities you handled, the exact activities you organized and executed to deliver results, and the overall outcomes. Put yourself in the position of a Hiring Manager, or HR leader, and show them (in professional language) what you did and why it relates to the working world.
To help you do this, I would search “Resume Words” or “Power Verbs” or “Action Verbs” and identify the best verbiage to articulate your experience. There are excellent lists available online, and using these to produce a well-written resume may help a recruiter or Hiring Manager take you more seriously, and land you an interview.
