Do you need a tawa for roti?

Excuse me, could you please clarify something for me? In the context of cooking roti, which is a type of flatbread, would you say that a tawa is a necessary tool to have on hand? I understand that some cooks may prefer using other utensils, but generally speaking, would the tawa be considered a standard or essential piece of equipment for making roti? I'm trying to gather information for a project and I'd appreciate your insights.
