Is kiosk mode available in 0.110

So I found that Home Assistant has support for a kiosk mode since 0.49(https://www.home-assistant.io/blog/2017/07/15/release-49/), but I am not able to enter it?..
I have tried to visit the URL hassio_local_ip:8123/kiosk/views_url_in_lovelace but without luck…
Always just getting a 404: Not Found message.
I’m using lovelace and 0.110. Is this functionality removed in a later release? Only finding separate scripts when searching for kiosk mode…

I think kiosk mode was removed long ago. There’s kiosk_mode in custom-header though.

oh, okay… thanks!
