For example, `page.getByRole('navigation').getByRole('link', { name: 'My projects' })` is a great way to find a "My projects" link that is nested under the `role="navigation"`/`<nav>` parent, especially if there are multiple links with the same accessible name on the page.

 Next on the list is the button that makes the whole form do something—the submit button. While I can select it by its text `'Apply discount'`, that would be quite a broad query. There can be _multiple elements_ with that same text on the page (e.g. a heading that also says "Apply discount"). A far more important desctiptor for this element is that _it is a button_.
