Is if fine for a bank to post clients' ID and info in Messenger Group chat of the company?

Hello,Not sure if this is the right group but might help.

I saw my bank branch employees sending clients' ID, Bank Card Pics, and other documents in the employee group chat in facebook messenger?

It seemed odd for me as those are confidential information to be seen by various people.

bank card chat clients confidential documents employee employees facebook facebook messenger hello info information messenger people privacy the company
