The "Eye" Icon for preview Office documents does not appear by default after configuring Office Server

STEPS TO REPRODUCE

1. Install a fresh instance of XWiki 9.5.1 with Office Server configured from "xwiki.properties" file
2. Login as Admin and confirm that Office Server State is "Connected"
3. Create a page and attach an Office document (or more)
4. Observe the Attachments section of the page

EXPECTED RESULTS

An "Eye" Icon appears next to "X" Button on the right of the attached file for previewing the document.

ACTUAL RESULTS

Only the "X" Button appears. However, the "Eye" Icon appears after installing the File Manager Application (and remains even if the application is uninstalled).
