WKWebView show modal from video with playsinline

I´m using a WkWebView in my application. There is a page that shows a video recorder inside the web app. It works on iOS 14.4, but it doesn´t on 14.7.1. In that version, it is shown a modal to broadcast video, and it is shown completely black. If you close that modal, the video recorder works fine inside the web page. So, what I need is that modal doesn´t appears, as in iOS 14.4.

In my log, I have seen the following lines:

<CATransformLayer: 0x281391640> - changing property masksToBounds in transform-only layer, will have no effect <CATransformLayer: 0x281396100> - changing property allowsGroupBlending in transform-only layer, will have no effect
