Copy and insert one polygon point

I am using exported polygon points in order to build a mesh in another software.
However, I need the first and last point of my polygon to be identical in order for the other software to recognize it as a closed polygon. So here is the question:

How do I copy one point in a polygon and insert it again in the same polygon? I need the point to be copied to be the first point in the attribute table, and the inserted (copied) point must be inserted at the end of the attribute table.
I need X, Y, and polygon ID to be identical.

I appreciate any advice you may have!

Thank you!
Best regards,
