is it even possible to have a bidirectional communication between two simultaneously running processes with run3?

No, IPC::Run3 doesn't support interactive communications with the subprocesses. IIRC, it does most of its I/O redirections via files, since that's the most portable.

If not what's the appropriate solution?

I've had success with IPC::Run. According to CPAN Testers it's not as portable, but so far I haven't had problems with it.
