Synthorial Fm Set Up in Phase Plant

Hi Syntorians!
I want to experiment making Fm patches in phase plant (like in syntorial Fm chapter), but I have a hard time to set it up! Especially the mod «fm» envelope!

For the fm (without mod env) I have modulated the phase of one oscillator by the other! (I don’t know if it is right)

Could you please help me?

Thank you
