You have Hombrew installed in a non-standard location. Mine is in
/usr/local/Cellar with the executables linked into /usr/local/bin.
But, assuming other Homebrew commands work when run from Terminal then you
might still be okay.

"Yes" to creating the path but "no" to copying. Create a symbolic link instead.
So, in Terminal:
$ cd $TEXROOT/tex/texmf-osx-64/bin/lib/luametatex/zint
# In my case I used the following:
$ ln -s /usr/local/Cellar/zint/2.10.0/lib/libzint.dylib libzint.so
# For you with Homebrew in a different location, try:
$ ln -s /opt/homebrew/Cellar/zint/2.10.0/lib/libzint.dylib libzint.so
Then steps 4 and 5 as below. I ran the MWE below: the ISBN worked, the ISBNX
didn't, the QR code did. This is on Monterey.
