Hey @guan404ming , the backend API has been merged. Could you please rebase from the main branch and see whether it works for the frontend?

the endpoints are detailed in #52868 (comment) and here're the example dags and the script to call rest API #52868 (comment)

Update: markdown render is enabled now for action body

Very very cool! Can you add some example Markdown to the hitl example Dag? Otherwise once the conflict is resolved I'd propose to get this merged!

Thanks for the review. I've resolved the conflict. I'll be working with @Jasperora to wrap up the UI-related docs. We'll add examples and handle the rest in the follow up PR.

I think to update, looks good overall and I think it's a solid base to start building on top of it.

The UI will need some polishing. And as mentioned other auth providers need to be updated or this will not show in the UI for those users.
