Hide the native navbar

[tontonduplaid]

Hello,
I tried to put this code in configuration.yaml and in the lovelace dashboard yaml, but I didn't managed to hide the native navbar.
Could you help me ?

ios-dark-mode-blue-red: app-header-background-color: transparent app-header-text-color: var(--primary-text-color) card-mod-theme: ios-dark-mode-blue-red card-mod-root-yaml: | .: | .toolbar > ha-tab-group { pointer-events: none; opacity: 0; }

Thanks a lot
F.
