Missing Approver Comments column in a SharePoint list

Question

Based from my testing, Approver Comments column is automatically added in a SharePoint list when Require content approval for submitted items? is set to Yes in Versioning Settings.

Now, I have 2 SharePoint lists and have problems with Approver Comments column.

In my First SharePoint list, I cannot find Approver Comments column - it is not showing in my column list when I try to show/hide columns. Therefore, it is not just simply hidden.

In my Second SharePoint list, I had an Approver Comments column. I played around with it and hid it. But now, I cannot find a way to show/unhide it.

What is the logic behind the Approver Comments column?

I cannot simply add a column with this name as SharePoint says there is already an existing column with that name or that name is reserved.

How to bring my Approver Comments column back in my lists?
