Iframe kiosk mode - what a pain!

okay guys so im 99% there with my project but iframes i just simply cant! spent around an hour before i thought i ask.

i have the url which works and tried and tested.
http://192.168.0.21:8123/lovelace/0lovelace/default_view?kiosk=title=

i have tried iframe for xibo using
iframe src=“http://192.168.0.21:8123/lovelace/0lovelace/default_view?kiosk=title=” name=“ha-main-window” >

and

i have added this to my config:

Example configuration.yaml entry

http:
use_x_forwarded_for: true
trusted_proxies:
MASKED -
- 127.0.0.1
- ::1
ip_ban_enabled: true
login_attempts_threshold: 5
use_x_frame_options: false

still no luck :frowning: any advice?
