|| : : This is a shell idiom. The || is a logical OR operator, and : is a no-operation command (it does nothing). This combination ensures that if meson test fails (returns a non-zero exit code), the function doesn’t return an error itself.

Failed to find a solution, I asked upstream at:
https://gitlab.gnome.org/World/Authenticator/-/issues/414
Maybe will give an answer latter.
