Good morning, Vinil! Invocation directly after "OK Google" or "Hey Google" is reserved for Google employees building Google-branded actions, so I doubt you'll be able to build this functionality.

You can, however, build an app that responds to something like, "Hey Google, talk to Super Awesome Phone App," where Super Awesome Phone App is the name of your app. Thereafter, you'll be able to handle a user's request to "call ABC."

If you want to build a telephony application for Google Assistant, you can refer to this sample and this codelab sequence.
