How to add oAuth profile for SOAP testing.

Hi I am able to find option to add oAuth profile for providing token to SOAP authentication. I tried both open source and Pro versions. In your documentation, it is asking to add oAuth profile as mentioned here but there is no such option. 

https://www.soapui.org/oauth2/oauth2-authorization/

I dont see any option to add oAuth in my latest version of SoapUI opensource. Here is the screenshot of my desktop program. 

Can someone help? its urgent.

regards

Fahad
