How to acces to the Icon font manager in a custom bric

Hi there!
I don’t know if my question is correct but: is there an API call to insert access the Icon Font Manager by a custom Bric? Or there are other ways?
I’ve trying to develop a custom bric and I want to let customers to choose an icon (by chosing one through Icon Font Manager) to insert into the bric (among other text fields).
Is it possible to achieve it?
Anyone knows a way to do that?
Thanks for your help.
