I'm a newbie Shopify app dev. How do i update app handle from TOML file? In this doc https://shopify.dev/docs/apps/tools/cli/configuration#global mentioned an option "handle" at the same place with "name, client_id" but when I try add this option the result when run "npm run deploy" as below:

So, What schema structure for this option "handle" is correct?
