I hosted app but don't see my checkout-extension

[Mark0601]

I have a problem with my extension. I created the app with command:`npm init @Shopify/app@latest," and then i just generated the checkout command:`npm run shopify app generate extension -- --type checkout_ui --name=my-checkout-ui-extension` and then I run command npm run deploy. i hosted my app to digital ocean and when I configured everything, I saw that in the admin panel, I see the test app with count and create 5 new products, but I don't see my extension checkout. 

maybe you need to configure something else. it will also be good if someone has done this and can share the complete instructions.  Also my extension work local
