Designer Created Columns for DataTables

I have a form using a DataTable. I used the older designer when I started development to create the multi line text field. The column is hidden. I now have a case in which I need to parse the data with Power Automate by I cannot figure out how to unhide the field. I have tried using Powershell with no success. Do you have any suggestions?
