It wasn't said what this Grimoire actually does, but "Me" said that it is the power to give shape to Es' feelings. The stronger her desire is, the more effective her power becomes. But it is a miracle that can be used only once.

Considering Hinata called Embryo her "feelings" at the end of CE, maybe this Grimoire let Es access Embryo's power for one last time? But this is just speculation.
