How do I lock phone by closing my case?

[Android Central Question]

I had gotten a Damsung case for my Note 10+ a while back. From the beginning when I would close the case the phone would lock. Today when I woke up it no longer does this. I've looked through settings and can't seem to find anything. How do I reactivate it? Could it be a problem with the case?

Welcome to Android Central! Is this a genuine Samsung case, or a 3rd party one?

Is this a magnetic case ?
