Child safety lock induction hob

Hello,

I am very sorry to write here now, but I am desperate and don’t know where else to turn.
I had a few friends over and they activated the child lock on my stove without me knowing.
The stove is used and I no longer have the manual.
I found nothing online that could solve the problem and I have tried everything.
I have already pressed all the buttons for several seconds and some simultaneously, without success.

I urgently need help.. I just want to make myself something to eat Dx
A picture of the control button is attached.

I would really appreciate any help!

okay I have a solution sorryy you can close the thread!! thanks

... as always, it would be polite to briefly describe the solution as well.

Oh, yes!

I turned on my stove and then pressed the two marked buttons for several seconds, then the child lock was gone.
