Describe the Bug

When I run the Nextcloud Docker container, everything works as expected. However, when I run it on Nextcloud FPM, the Nextcloud Assistant shows as 'Enabled,' but the Nextcloud icon does not appear in the navigation bar and seems unusable.

Expected Behavior

I expected Nextcloud to work on Nextcloud FPM as it does on the regular Nextcloud image

To Reproduce

Run Docker Compose with the latest versions of Nextcloud FPM, Nginx, Bitnami MariaDB, and OnlyOffice.
