Except for something like flatpak, it doesn't actually exist in the PATH I believe.

This is the function that Lutris uses:

def get_umu_path() -> str:
    """Returns the path to the Umu launch script, which can be run to execute
    a Proton version. It can supply a default Proton, but if the env-var PROTONPATH
    is set this will direct it to a specific Proton installation.

    The path that this returns will be considered an Umu path by is_umu_path().

    If this script can't be found this will raise MissingExecutableError."""

    # 'umu-run' is normally the entry point, and is a zipapp full of Python code. But
    # We used to ship a directory of loose files, and the entry point then is 'umu_run.py'
    entry_points = ["umu-run", "umu_run.py"]

    custom_path = settings.read_setting("umu_path")
    if custom_path:
        for entry_point in entry_points:
            entry_path = os.path.join(custom_path, entry_point)
            if system.path_exists(entry_path):
                return entry_path

    # We only use 'umu-run' when searching the path since that's the command
    # line entry point.
    if system.can_find_executable("umu-run"):
        return system.find_required_executable("umu-run")
    path_candidates = (
        "/app/share",  # prioritize flatpak due to non-rolling release distros
        "/usr/local/share",
        "/usr/share",
        "/opt",
        settings.RUNTIME_DIR,
    )
    for path_candidate in path_candidates:
        for entry_point in entry_points:
            entry_path = os.path.join(path_candidate, "umu", entry_point)
            if system.path_exists(entry_path):
                return entry_path
    raise MissingExecutableError("Install umu to use Proton")
