How to debug under UC Browser iOS?

Question

iOS

Found out that my JS code is not working in UC Browser under iOS. It just doesn't work silently, that's all. Where, how to look at the errors - no idea.
Googled - on the Internet only debugging options in "native" pairs (Safari-Safari, Chrome-Android) are described.
In principle, the browser is not a very priority (I think it is used by a little more than anyone under iOS, unlike Android), but nevertheless?
Maybe someone came across.
