Gimp resynthesizer heal selection missing

The gimp resynthesizer heal selection tool is missing.

There is much online discussion about the fact that it relies on the old Python2, which no longer available for a traditional Apt install method. I tried the Snap of Gimp, hoping that it would include the old Python2 stuff, but I still can’t get resynthesizer heal selection to appear & work.

Is this fixable? Rumor is that the AppImage works, but I’d rather use the Snap if possible.
