Hi. Is there a way to put a field to "i have read and accept the privacy policy" and it be Required?

Hi. Need more details. It is not clear how you want to use this field.

I need to put a advertise and a checkbox to 'i read and agree with..' in a blog post. And needed to BE required...

From your words, I don’t understand where this field should be, in the frontend or backend. If you need this field in the frontend, then how to understand which user agreed to the condition? Please specify the task in more detail.
