Insert icon into text

Dear all, on my previous website, I used an icon to designate an outgoing link by adding like <i class =“fa-solid fa-arrow … to the text part of a rich text element.
Now, with Bricks I understand how to add an icon to a block and so on, but I cannot figure out how to add an icon INTO a text. Can someone explain please? Thanks a lot.
