FinBoard reports are always created in your private Google Drive. To share this report with other users, you can either:
1. Manually share the report through Google Sheets "share" functionality
2. Or move the report to a folder that is already shared with other users
Please note: User access to a specific company allows them to create report for that company. It doesn't give them access to the existing spreadsheets or new spreadsheets unless you share it with them.
