Learning Approver Column in BI Publisher and ApplicationDB_HCM

Summary

What is the column where you will see the name of who approved the learning assignment of the employee?

Content

There is a requirement where we need to know the name of the one who approved the learning item of the learner and create a report/analysis with it.

The problem is we do not know what name it uses in the BI Publisher and in the ApplicationDB_HCM table.

Is there a column that is close to the term "approver" both in BI Publisher and in the database?
