Another three steps workflow :
1. Colors > Curves...
- select channel Alpha
- inverse the curve : move the bottom left point to the top left and the top right point to the bottom right
2. use Fuzzy Select with these settings
- Mode: add to current selection
- Select transparent areas checked
- Diagonal neighbors checked
- Threshold 255.0
- Select By : Alpha
to select the exterior areas of the subject
3. Edit > Clear

PixLab, I had problems with the image provided by the OP.
Image as seen after fuzzy select a transparent area.
In addition to the lack of uniformity in the background transparency, the contour always presented a pixelation not shown in the other results exposed here on the forum.
So I changed the image before testing the steps.

By superimposing the final result (the opposite image) over the contours of the initial image, with a red layer in the background, it is possible to see a small gap generated in this process.
At least in my tests, only the procedure suggested by
Denzjos did not present this gap.
