Publishing operator made with KOPF on RedHat Marketplace

I have made an operator for my platform/application.
For convenience, I had used the KPOF (https://github.com/nolar/kopf) to write my operator logic.

Now I wish to publish my operator on RedHat Market place but I can't find proper resources regarding pythonic operators (or operators apart from GO).

As per my research I found a few resources and currently following the following article to make the bundle:

This article uses Operator SDK and Kustomize but I am getting stuck with some config errors and some internal errors.

So I would like to know if there's some direct step-by-step guide to publish the non-GO based Operators on RedHat Marketplace.
