UI Builder Australia: Public access to specific pages while keeping the host Experience protected

[BachuRavikumar]

Hi Community,

I am using ServiceNow Australia UI Builder. I need help allowing anonymous users to access specific pages in an existing Experience without login.

Requirement:
External quiz participants should open the Join Quiz and Participant Buzzer pages through a QR code. The host's Stopwatch Home page must remain protected and require login.

Existing pages:

• Join Quiz: /join-quiz/{code}

• Participant Buzzer: /participant-buzzer/{code}

• Stopwatch Home: host controls

I configured Public audience on the Join Quiz page variant and created page-specific ACLs:

• x.1892173.stopwatch-experience.join-quiz (ux_page, read, public role)

• x.1892173.stopwatch-experience.join-quiz.* (ux_route, read, public role)

The existing now.stopwatch-experience.* route ACL requires canvas_user.

When I open the Join Quiz URL in an Incognito window, it redirects to the ServiceNow login page. I tested a separate public Experience, which opens without login.

My questions:

1. Can the existing canvas_user route ACL prevent anonymous access despite the page-specific public ACLs?

2. How can I allow public access only to Join Quiz and Participant Buzzer while keeping the host page protected?

3. Is a separate public Experience the recommended solution?

Thank you.
