Does Zeus support custom subscription?

[vu-innoflex]

Hi guys,

I'm following this https://graphqleditor.com/docs/zeus/custom-fetch/ to implement my own custom fetch.

But then I'm stuck at implement custom subscription. Have been digging around but found nothing.

https://github.com/graphql-editor/graphql-zeus/blob/3455b762a7d3072a5a77b1024c3ccb9a19277997/examples/typescript-node/src/zeus/index.ts#L202

This SubscriptionThunder class seems to be the closest one I found, however it only allow query as parameters, while in my case I need to pass variables as well

Hence, my question. Does Zeus support custom subscription, using that class, or I'm missing something here?
