How to use google API to make a video call from hangouts directly to another email

Question

I would like to integrate a video call feature on my website. If I integrate the following code:

I am able to invoke hangouts. But this requires users to type in the email ID of the people they would like to make a video call.

How can I automate this manual step? Is there a way to pass the email Id to the above code, so it automatically calls the other person.

Thank you

As of Now, this is not possible. Hangouts Chat API is only used to create chatbots and you could start a conversation with a specific user.
