How can I provide access to reports to my colleagues?

Are you referring to the form submissions? If yes, then you can add them as a sub-user of your account. Here's a guide: How-to-Share-Forms-with-a-Sub-Account-User.

You may also share the submissions page itself, here's how: How-to-Share-Form-s-Submissions-Page.

Normally, if you created a report (HTML Table Listing, Grid Report, or Visual Report), there is an option to share the URL or embed codes at the end of the wizard.

Hope that helps. If you have any questions, let us know. Thank you.
