How to use Arena with an AppGateway

[JoJ123]

Hi,
we are using an AzureAppGateway for our WebApps.

WebApp1: (basePath: /app-runer)
https://test.my-domain.com/api/...

I tried the following:
const arena = ...
{ disableListen: true, basePath: "/api" }
app.use('/bull-arena', arena);

With this setting the Arena is not loading anymore at all under this url:
https://test.my-domain.com/api/bull-arena/

When I remove the base path from the config:
{ disableListen: true }
I can reach out the Arena, but no of the Links are working as they don't include the /api

@skeggse Is there no solution?
We are also using bull-dash it's working fine there, but both libraries have their benefits :)
