Live interactive sessions?

Hi there, I am totally new to this and am thinking of creating my first course. I'm a professional academic with loads of experience generally, but not with Udemy at all.

So, for my first toe in the water, I thought of a short, say 5 week course, on a classic text in my field. But I also was hoping to have a live interactive element, assuming the numbers are not massive, where each student could ask me a question, or the best questions get answered, or questions are voted on, etc. Can I do that kind of thing or is Udemy just fully pre-recorded and non-interactive?

All help and tips welcome!

Thanks,

David
