+2. Tracks all file sharing activities in Microsoft Teams Channels across your tenant.
+3. Finds files shared by external users in Microsoft Teams.
+4. The script can be executed with an MFA-enabled account as well.
+5. Finds files shared in a specific team and channel.
+6. It exports the report result to CSV format.
+7. It can be executed with Certificate-based Authentication too.
+8. The script is scheduler friendly.
