Can't turn my public app into sales channel

I am trying to use Storefron GraphQL in a public app. As stated in documentation https://shopify.dev/api/storefront/getting-started#requirements, my app should be turned into sales channel. However, this is not working from the app settings https://www.loom.com/share/814da2c64af5439e8dc9ba804839920c. I believe this is the reason I am getting ACCESS_DENIED code when trying to request graphQL.

mutation {
  storefrontAccessTokenCreate(input: {
    title: "Pact Act"
  }) {
    storefrontAccessToken {
      accessToken
    }
    userErrors {
      field
      message
    }
  }
}

Today I checked my app and it became a sales channel. No idea how.
