Code PIN de mon espace privé oublié / inutilisable?

Hello,
On my Fairphone 5 (IodéOS 7.2), I want to access to my private space to see if there are some Apps hidden in it. The system asks me for a PIN code, but none of the ones I could have used are valid. Actuallay, I don’t remember if I locked the private space wit ha PIN code when I discovered my new phone, bit I guess so, as it is locked.
Is there a solution to unblock this?
Thank you

If you want to wipe out your “Private Space” then I think that can be done this way “settings → security & privacy → private spaces → delete private space”
