Expo gl 3d interactive obj model

I want to add interactive obj model in my app, which can be rotated, zoomed just like a 3d model.
I check expo gl view but that provides index.js, but i want app.js



What do you mean when you say “but that provides index.js” and what exactly do you mean by “but I want app.js”?

Sir! I am talking about expo documentation. They have provided and example with a depository link. But that link elaborates web procedure i.e. index.js. But I am using Visual code-Expo which requires app.js.

Can you simply guide me to implement obj model in my app?
