L298 schematic to control 20V DC motor

Hello,
Are those schematics ok for a l298? I found it on the l298 datasheet and my motor is supplied with 20 V and absorbs 0.2 A. How can I design R sense? Do I need heatsinker?

Do you intend to monitor the current level? If not then bypass the shunt resistor
(ie use a zero ohm shunt).

Yes, heatsink advised, but for a 0.2A motor you might get away without one.

Well, what do you think is the answer to that question?
