What

1. Background - why this is needed
2. What did you do
3. What does the reviewers should expect

I have done:

• Updated relevant documentation

I have tested manually:

• The feature's functionality is working as expected on Chrome, Firefox, Safari and Edge
• The screen reader reads and flows through the elements as expected.
• There are no new errors in the browser console coming from this PR.
• When visual test is not added, it renders correctly on different browsers and mobile viewports (Safari, Firefox, small mobile viewport, tablet)
• The Playground feature is working as expected

Hey, had a quick look, I think there are a few things definitely wrong, and some I am now sure about, I think might be getting a bit messy. We can have a look tmr 👍

If you can add some description, and links to useful related pipelines to have a look at would help me tmr 🙏
