Hi @PedroGomez-Rami ...
If you are a Canvas administrator for your school's Canvas environment, you can reach out to your assigned Customer Success Team at Instructure, and they should be able to help you. Check out the information in the light-blue box at the top of this Guide for more information:
How do I use Commons? - Instructure Community (canvaslms.com)
Hope this helps a bit! Let Community members know if we can be of further help.
