Can I host an event with zoom meeting instead of zoom webinar?

Hi everyone,

I am planning to host an event, for around 20-100 people,  and would like them to join just as a participant, such that no one sees the number of participants, and can only chat publicly in the chat section.

Do I have to use Zoom webinar for this purpose, or can I do this using Zoom Meeting? 

Or is there any other mode I am not aware of?

Thank you for your help,

Maria
