How to connect eSkate vesc app

So I just transferred to an iPhone 8 from android. Had Ackmaniac’s firmware and app working there just fine.

Just bought your app but don’t seem to know what to do. I’ve tried to choose the Bluetooth module but I don’t see it. Do I connect via the phone’s settings for Bluetooth or only through the app like Ackmaniac’s?

Any ideas/guides to follow here?
