You might be better off using Gimp 2.10, the filters work directly on the canvas.
Maybe something like this:
I put the screenshots all-on-one so please refer: https://i.imgur.com/3hROxYq.jpg
1. Add a transparent layer on top Layer -> New Layer
2. A bit of artistic licence required, paint in some stripes for shadows.
3. Give that a good blur Filters -> Blur -> Gaussian Blur
4. Switch to the banner layer
5. The difficult one. Filters -> Map -> Displace Click on Aux 2 input, and choose the shadow layer. Break the link between horizontal and Vertical and adjust the Vertical Displacement a little.
6. Reduce the opacity of the shadow layer as required.
Might look better with slightly wavy edges, you can do that with the warp tool.
