Open some url in native browser

Hello, I tried a few options but nothing to work.
I’m loading article content from API to my Ionic application. Some content contains “a” tags and I would like to open it in native browser on device.

I tried InAppBrowser but it’s doesn’t work.
Some tutorial rewrite window.open with cordova.InAppBrowser.open but cordova is undefined in my case.

I don’t know how can I do it.

Thx a lot

ionic version 3.4.0
cordova version 7.0.1
