PS/2 Keyboard to WEMOS Board

Has anyone ever tried to connect a PS/2 Keyboard to a Wemos D1 R2 board?
I've read it's not straight forward like in an Arduino (ps2 library not working with ESP), so I was wondering if anyone here has tried.

I need an external keyboard to input alphanumeric characters so the operator can identify a shipping ID in a Wemos Board so this ID + some other read data is sent to network.

Can anyone help?

Thank you in advance!
