What is user agent in webview kodular?

What is user agent is kodular?

I am using this user agent - Mozilla/5.0 (Linux; Android 9.0; Pixel3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.80 Mobile Safari/537.36

From my apparent knowledge this user agent belongs to chrome. I want to know will the browser load if the user does not have chrome app installed?

I am using this user agent so that google allows google login via app. But From my experiments I have tested, that if I type anything ‘xyz’, in the user agent, then web browser also load and also allows google login.

Can anyone explain me this?

Thanks in advance.
