Urgent! Question About Attesa Occupazzione

Hi,

I have been living in Italy with a study permit. I have graduated in July2020, and my study permit has expired in august 2020. I have applied for attesa occupazzione. When I went for the fingerprints, they have told me that I have a missing document which is: health insurance. (assicurazione sanitaria). And they took my fingerprints and they gave me extra time and another appointment to collect the missing document.

As far as I know and according to my researches, if you apply for Attesa Occupazzione you do not give the health insurance. Does anyone know if the rule has been changed or they did a mistake? What can I do to be sure if everything is okay there? Because I also found a job, and I need to convert attesa occupazzione to work permit in the future, but I am so scared that maybe the guys there made a mistake and they considered my application as another type of residence permit application which may not be convertable to work permit

Can you help me guys? How I can understand what's going on.

Thank you for your helps!!! Have a great day!
