Showing my website containing adsense through chrome custom tab

Hello. I am making an app introducing information.
This app contains some part of information. Users who need more information can click ‘more’ button and I will show them my website.

I was wondering if I can show them my website which has adsense ad on my app. Because my app has admob ads. I’ve heard that showing website which has adsense through webview is against google ad poicy if your app has admob ads. Therefore, I will show my website through chrome custom tab. Will this way be against google ad policy or causes any other problem?

I’ve searched a lot and questioned on admob community but I haven’t got any answer.
