How do I change Photoprism config options, specifically wakeup-interval using the plugin on OMV?

I've tried several variations based on some other threads but how do I change a config option, specifically wakeup-interval on the Photoprism plugin? It is currently at 15m0s by default but I would like to change it to 6 hours. I have OMV installed "bare metal" on a HP Proliant machine.

Some commands I've tried:

sudo podman exec photoprism-app photoprism config set PHOTOPRISM_WAKEUP_INTERVAL 21600

sudo podman exec -ti photoprism-app photoprism PHOTOPRISM_WAKEUP_INTERVAL 21600

sudo podman exec -ti photoprism-app photoprism wakeup-interval 21600

sudo podman exec photoprism-app photoprism PHOTOPRISM_WAKEUP_INTERVAL 21600

sudo podman exec photoprism-app photoprism wakeup-interval 21600

sudo podman exec photoprism-app photoprism wakeup-interval 21600

Commands that do work:

sudo podman exec photoprism-app photoprism help

sudo podman exec photoprism-app photoprism config

After looking into your suggestion this seems to be the answer, but I'm still missing something. Using WeTTY, I ran the following commands but when showing the config options afterward, it doesn't seem to have changed? Value next to wakeup-interval is still 15m0s.

Seems I need to be in /etc/default/openmediavault but do not have those permissions.

# omv-env set -- OMV_PHOTOPRISM_APP_CONTAINER_START_OPTIONS "-e PHOTOPRISM_WAKEUP_INTERVAL=21600"

# omv-salt stage run prepare

# omv-salt deploy run photoprism

Command used to check config values sudo podman exec photoprism-app photoprism show config
