App authorized just for presenting account user, not for invitee account users

Our company has a Business Zoom account.  I added a meeting 'engagement' app to post polls, ice-breaker questions for the training calls I conduct.  In testing the app, a fellow user under our business license properly logged into the meeting and when I launched the app received a message stating they were considered an anonymous user and needed to log-in properly, which they were properly logged in.  Does this mean that all apps to work for invitees/audience has to be added to each of their accounts?  I'm using the Polly app.  Would appreciate some guidance.  Thanks!
