curved image (how do I stretch)

GIMP Version: 2.8.14
Operating System: Linux
GIMP Experience: Intermediate Level
Hello to all.
I need experts help, I have a picture of a photo, the picture was taken with the photograph curved and I cannot modify to make it look flat (the contents are important, it is an old family photo). Can it be done without open heart surgery?

You can try "Lens Distortion" in the Filters>Distort menu.

A few more hints. Save as you go. Use the Colors > Curves tool to lighten a dark image. G'MIC > Details > Freaky Details can bring back some of the lost information

Not sure the lens distortion is an adequate transform, we would need something that "unrolls" the picture:

It worked (some) but better with the distortion with curved lines. Thank you for the tips.
