LMG2100R044: Integrated transistor freewheeling diode capacity

Part Number: LMG2100R044

I'd like to know the current capacity for freewheeling diodes integrated to GaN transistors in the card. We're working a CHB topology to feed an electric engine and we have the concern about the necessity of integrate freewheeling diodes external to the ones integrated in the design to avoid damage for return currents. The data sheet says the zero reference recovery inherent to GaN transistors is enough to avoid this issue, but we'd like to be sure it is.
