LM5046: LM5046 drive primary side GaN FET

Hi,

My customer would like use LM5046 to driver bothe Primary/Secondary side GaN FET, from secondary side we suggest LMG1210 to drive GaN FET but for Primary side can customer driver GaN FET directly?  or customer still need LMG1210?  and how to connect from LM5046 to LMG1210 as signal level is different?

Thanks.

Eddie
