The usual comment, all depends on the images. Very different in shading and orientation is a problem but here you stand as good a chance with gmic as anything.
This a quick demo, spend a bit more time and get a better result.
1. A bit of preparation if required - sizing - cropping - a bit of erase.
2. Into the target image, move and generally fit in place
3. Apply gmic and adjusr parameters.
4. If needed a bit of clone tool on any obvious edges
A 3 minute demo of the above. https://youtu.be/G-1jL8JhStQ
