How do I manage to ask more questions?

Hey dear community

I (f13) am currently doing a trial (which means I'm getting to know a profession). I'm doing a trial as a childcare professional (FABE).

I've already had a look around at this company. At the final interview, the only thing she criticized was that I didn't ask any questions. The rest of the process was very good, or at least good.

I also asked (almost) no questions this week. ):

I don't know exactly why I have such a problem asking questions. I also know what kind of questions I want to ask, but I don't dare.

Do you have any tips to help me feel confident asking questions?

Thank you in advance for your answers!
greetings <33

PS: The tip "Just ask" doesn't help. ( ;
