Google API Authentication & REST Nodes

I use a lot of APIs from Google, all which require access tokens. I have a lot of daily data ingestion jobs I would like to move to KNIME Hub for automation. Today, the Palladian OAuth nodes + REST execution work perfectly for what I need when I run locally, but the Palladian nodes aren’t available on Hub. I tried using the Google Authenticator with a JSON API Key, but I can’t get that to work with REST. I need the flexibility of REST over built in nodes like Drive or Analytics because those don’t allow for the customization I need for the requests.

I see someone else had a similar request here: Can't connect to Google Cloud API (others than those with specific nodes)

Any solutions? Or can I enter a huge plea to have a way to license Palladian Nodes for Hub?
