Custom cookie policy link inside cookie solution

I need to add a custom privacy policy link inside an already existing banner.
With the old view, it was possible, with the new one the option only appears if I delete the linked Iubenda Cookie/Privacy policy.

I give you an example.

I have my website with a custom privacy policy.
I want to use Iubenda cookie solutions and Iubenda Cookie policy.
I have created all my setup not knowing that the option i need only appears under some condition.
How can i add a link in my cookie solution which points to an external link (i.e a webpage of my website itself).
