This is a follow up on what you have , and knowing what you want you have pulled something inappropriate from the internet. There are as previous easier ways but it might help you/others in future.
This your graphic. I found the original svg and you can open it both as a graphic and Gimp paths. The import dialogue you get: https://i.imgur.com/FQpnuBE.jpg
Opened in Gimp the original artist has traced the paths as a graphic. This is just a representation of the paths for the internet. They are pixels on a transparent canvas. https://i.imgur.com/OkzFG5b.jpg
You do not really need that layer, all you need are the paths. This a new white layer on top so we can see the paths and those now made visible (the eye icon). https://i.imgur.com/qw8bNRD.jpg
Looks similar to the graphic. Red is an active path. blue is an inactive path. Both only exist in Gimp. They are saved with an .xcf file but not exported with png / jpeg...
What to do with those. I do not know your intention. They can be combined in selections like this, to give a slightly distorted outline. https://i.imgur.com/3TAz4mc.jpg and then used to cut the image.
