Amiel left the President's office to co-write an essay Le progrès ne tombe pas du ciel (English: Progress doesn't fall from the sky) with Ismaël Emelien.

[5] The work, which sold 3,700 copies, was received dryly by critics who suggested that it was low on substance in favor of absolute support of the President's actions.

Amiel opposed the Tour Triangle, campaigned in support of the opening of Rue du Commerce on Sundays and worked on security problems in Beaugrenelle.

[8] At the same time, Amiel began work at La Poste, but left the job after less than a year to join President Macron's re-election campaign in the 2022 presidential election.
