How to require indico users to accept legal disclaimers?

Hello the list,

I would like to know how I can make indico users to accept legal disclaimers (Administration —> General Settings —> Security —> Legal/Disclaimers) when they create an account (by themselves) to register for an event (e.g. a conference)? I’m managing my own instance of indico (version 2.1.7).

I would really appreciate your help.
