IOnic3 Video call Integration

I want to integrate one to one video call feature to the Ionic3 project, it should support all platforms like WEB, Android, IOS. I tried so many APIs like VONAGE, PUBNUB-WebRtc, ZohoDesk, OPenTok,Enablex. But all libraries are supporting only mobile platforms through Ionic, those are not supporting on the web. Can anyone help to do this.
thankyou

Hi, I found an article which have listed the top Video Call APIs and SDKs Providers for both mobile and web apps : https://morioh.com/p/7f4b1c7df5be

thankyou,
But we have used APIRTC (APIZEE) library for implement video call.
