Placeholders for login self hosted widget

Questions

Hi Team

Placeholders for input fields are not reflected,

I wanted to update placeholders for the login widget with the below configuration, I don’t see any placeholders.

Requirement is my design wants placeholders for inputs instead of labels, to take less space in the form.

i18n: {

        en: {

          "primaryauth.title": "Sign in",

          "primaryauth.username.placeholder": "Email",

          "primaryauth.password.placeholder": "Password",

        },

      },

How/where are you testing this: in a self-hosted widget or in the Okta-hosted customized widget that you can configure with a custom url domain set up for your org?

What does the complete widget config look like, and/or how are you configuring the i18n within the config?
