How to tell just where to find sh? (but not in recipe!)

On my Windows install I'm using Git Bash, which has as sh.exe, but it's not in my PATH (and I do not want it in my PATH). So how can I tell just where it can find that sh.exe?

I've looked at the docs but the only examples I see are using things like shell and windows-shell which are options that have to be added to the recipe. But that would make the recipe not usable by others, so that's not an option.

Edit: also on Windows 11 bash is available by default, but sh isn't

Edit2: a solution would be to add the Git Bash bin folder to the Windows user or system PATH, but then I'd be overriding the default bash that comes with Windows, which is not what I want. And I've seen the discussion where JUST_SHELL was suggested and rejected but perhaps a solution would be to have a JUST_SH_PATH option. That way just files will always be able to find the correct binary, even when running just files from within other just files.

Note that Windows 11 bash.exe is WSL, not bash on Windows. So IMO it's not viable, because bash.exe is calling out to the WSL virtual machine and might invoke a totally different shell (fish, zsh, etc), might not have access to the Windows working directory, depending on the host's WSL configuration.

Indeed, which is why a JUST_SH_PATH option would be useful to tell just where the correct bash can be found. It's an env var that could easily be added to the system or user env vars and it won't adversely affect anything on the system and it will make just files that depend on sh work on Windows.
