Cannot get out of lovelace custom header kiosk mode

Hello
I am currently using version 0.108.
I wanted to experiment with custom header kiosk mode but did it on the admin user.
Now i am stuck in kiosk mode and cannot access the normal front-end anymore.
I found 1 post about this problem where the solution proposed is to use the following adres in the browser : http://192.168.1.21:8123/lovelace/0?disable_cch
Unfortunately this does not work and it stays in kiosk mode
Can somebody help ?
Thanks in advance

Hello
Thanks for your quick reaction
Unfortunately this command http://192.168.1.21:8123/lovelace/0?disable_cch
does not work in my system change the “0?” with “1?” or “2?” show the pages 1 and 2 but all in kiosk mode !!!
Could it be related to the latest 0.108 version ?

Oups : the command is http://192.168.1.21:8123/lovelace/0?disable_ch and not http://192.168.1.21:8123/lovelace/0?disable_cch
Thanks for your time !!
