Issue Summary

When a JSM Portal Customer logs in with their portal account and tries to access a Confluence page that has anonymous access enabled, the page tree doesn't load with error "Content Tree failed to load", Try again.

The page is accessible to truly anonymous (not logged-in) users, but fails for Portal Customer accounts.

Steps to Reproduce

1. Create a JSM project on a Confluence-connected site.
2. Add a new customer to the JSM project using an email not linked to an existing Atlassian account (this creates a Portal Customer account).
3. In Confluence, navigate to any space → Space Settings → General → Permissions and enable anonymous access.
4. Confirm the anonymous page is accessible in an incognito/private browser window (not logged in) — it should load fine.
5. Open a new browser session and log in to the JSM Customer Portal using the Portal Customer account created in Step 2.
6. From that same logged-in session, try to access the anonymous Confluence page URL directly.

Expected Results

The Portal Customer should be able to view the Confluence page, since it has anonymous access enabled and is viewable by anyone — including unauthenticated users.

Actual Results

The page fails to load. The GraphQL response returns a 403 in DEV console 

 {
      "message": "Service confluence_page_tree does not support customer accounts",
      " "statusCode": 403, } 

UI shows Content tree failed to load.

Workaround

Request the Portal customer to login to Anonymous pages from incognito where they are not logged in with their Portal Customer account.
