I am having an issue using cart-checkout-validation extension in my app. I have created the extension using javascript and been through all the steps included in article => https://shopify.dev/docs/apps/checkout/validation/server-side
I was able to create the extension after upgrading my node, npm and shopifyCli to the latest version. After initiation i updated the graphql query and run.js according to the documentation, and i was able to push it to my store and app in shopify admin. I can see the extension in the extensions tab and on npm run dev i can see in the terminal that building shopify function and pushing the draft extension was successful.
Now the main issue is that on the third step where i go to the settings/Checkout and at the bottom there should be a section named Checkout Rules containing my extension cart-checkout-validation as an option to select and implement but i have tried a bunch of options, read different blogs and even tried making the extension with typescript or reinstalling again.
Additionally at first i tried it once on a previous store with no checkout extensibility preview enabled but have tried multiple times on a new store with checkout extensibility preview enabled but still the scenario is not changing on the third step.
Kindly review it and let me know what i am missing or is there something needed to be done from shopify support end.
