Run app with Capacitor in AOSP?

Anybody know how to run Ionic + Capacitor app in ‘AOSP’ android ( without gapps: gPlay, etc )?
My app work in “googled” OS but in clean version app show only white screen. I try to install latest Chrome and Webview and nothing change.

From docs

Capacitor requires an Android WebView with Chrome version 50 or later.

window.navigator.userAgent in app return
Mozilla/5.0 (Linux; Android 9; Android SDK built for x86_64 Build/PSR1.180720.012; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/66.0.3359.158 Mobile Safari/537.36
Why it not work? Do I need install something?
