My old job is going private and I have ESPP shares. Do I have to sell? How does this work?

I currently own a few thousand dollars worth of shares from my last job by using their espp program. They just got bought out and are going private in Q2. What does this mean for me? Do I have to sell my shares before this happens? If not, should I? Will it automatically happen or do I need to sell them the normal way? I have no knowledge of what to do in this situation and what it means for me.

Thanks in advance!
