Hello, @torres_b Welcome to the Canvas Community! We see that you're using a Free For Teachers account, and we've double-checked the FFT account settings to ensure that Direct Share is enabled for all Free For Teachers users (it is). I took a peek at one of your courses and can see the Send to and Copy to options next to quizzes.
So this will need closer examination by a support agent. Please use the Report a Problem link on the Help menu to ask Canvas Support to investigate (How do I get help with Canvas as an instructor?).
