Thanks for the good customer service.

This is Wacom hardware, and Wacom software, and you already have the Wacom answer.
This configuration is not supported.
You’re seemingly now shopping for an answer that you like better.
You're left to use a hardware and software configuration that is supported, and/or to lobby Wacom to add support for this hardware and software on Catalina, and/or to research alternative products and options.
I’ve run a DuckDuckGo search for the obvious string, and have turned up a potential work-around from folks over on Reddit:

This Wacom device is apparently out of production and out of support, which means scrounging for options and for help prior to its eventual replacement.
Depending on local requirements and budget, one potential replacement option is iPad and Pencil and Sidecar:
