YES!! I was able to use this new OAuth Connector [BETA] to successfully authenticate with Google Search Console Webmasters API and make POST Requests.

I’ll follow up on the subsequent tasks/workflow in this thread here - Having difficulties setting up Post Request to Google API requiring OAuth2.0 - #14 by qqilihq.
Thank you @qqilihq for great features and community support.
