How to redirect to the editing mode after adding a post

Hi,

Currently, after adding a post the success message is shown, together with a new empty form.
What I want is that after adding the post, the same post is shown in edit mode in the frontend. I have a separate edit page (/edit-profile/).
From the documentation I understand that I should use the hook rwmb_frontend_after_process.
How do I adapt the hook to redirect to the edit page?
And, I need to add the php code of the hook to the theme's functions.php file, right?

Can you help me with the correct php code?
