Insert forms shortcodes in restrictited access message

Hello,
I’m trying to setup restricted access message.
I’d like to display something like :
“This page is restricted to registered users. If you already have an account, please login [and here display the login form] or create an account [display registration form here]”

However, when I insert the form shortcodes in this area, they are just displayed on the page, and no form appear.

Could you please help me ?

Thanks
