Typically you will just need adequately rated wire. Your lab may have rules about the type and rating of the wire.
You can generally use jacketed wire (like a 3 phase extension cord), or loose wire in conduit. If there is going to be significant vibration at the motor you will probably want to use stranded wire instead of solid.
Keep the wire runs as short as possible.
Run grounds, don't use a 2 phase extension cord with the green as the third phase with no ground. Don't use green as the third phase under any circumstances.
The extension cord you linked in was a 2 phase 10/3 cord, you need a 10/4 cord. Something like this:

Probably easiest to get something with the correct plug for your 50A 3 phase outlet and get it long enough that you can cut it in half and use the tail between the VFD and the motor.
