How to change the texts on the login page?

Hi ;

How to change the « Username and e-mail address » text and « Example: » text on the login page in my Peertube example?

I don’t know. I noticed that it’s an input element with the ID ‹ username ›. I thought this would work but it doesn’t:

Customizations → JavaScript

const emailField = document.getElementById('username');
emailField.placeholder = "new text here";

I’m not sure where and when this is executed. Maybe someone can take it from here.

I just want to change the texts in the marked places in the picture I shared with you.
