Smartthings component via Tor?

I’ve been using the Smartthings component using the documented method (Duckdns, Letsencrypt, etc.) for a while, but I would like to see if I can do it with Tor instead. I’ve got the Tor hidden service set up and can access my Homeassistant instance via the .onion URL, so it’s all good so far. But I need some guidance on how to configure Smartthings to push its updates through Tor instead of the path. Has anyone here done this? Is there some documentation somewhere that would help me on this last piece? Thanks in advance.
