Thank you @ShivangShandilya 🥇 , can you please make a cherry pick and also push the change towards main, so that we can keep it in next docs versions?

Sure @RealAnna but looks like crd template is not available in main. So, I'll have to create this file in crd yaml ref. Do you want me to raise an issue for this or I can directly open up a PR directing it towards this very same issue?

@ShivangShandilya, this is curious.... yes please use the same issue 😺
