Checkout UI extension not working,

Hello!
I am trying to build a checkout UI extension app. While developing the extension using shopify app dev command the extension preview works on the development store, But once I deployed extension using shopify app deploy command. The extension is not visible in the checkout customisation UI. What could go wrong ? Do I need to have Shopify plus store to test it ? Any help will be appreciated.

Thanks

Hi @Akash_Pate

Are you deploying onto a dev store that has the Checkout and Customer Accounts Extensibility developer preview enabled? See: Start building for checkout

Thanks @Liam-Shopify
My dev store was not enabled for checkout & customer account extensibility developer preview. It is working now. Thanks
