Sharing a sheet / report with a person outside your organization

Hi all,

I did a few searches, but I can't find the answer to my question. We work with some suppliers who we would like to access specific sheets or reports in Smartsheet. We tried sharing the sheet / report with the email address of the individual, and it's asking them to make a smartsheet account. Is there a way you can share a sheet without an account? How are other users handling this situation?

Thank you!
