Connecting the output of the Google Authenticator Node into a own Python based KNIME Node

Hello,

I‘m trying to create a new Python based KNIME Node with this documentation. Create a New Python based KNIME Extension

My goal is to connect the output port from the Google Authenticator Node (Extension: KNIME Google Connectors) into my new node as an input.

I was wondering if there is any way to build an input port so I can use the credentials a user gets from the Google Authenticator Node.

I tried using a custom port object without any luck so far. (Create a New Python based KNIME Extension)

Best regards
