The Cairo giants had already reached an agreement with Flambeau to play both legs in Egypt.
The five-time African champions qualified for the second preliminary round after beating Chad's Elect-Sport 4-0 on aggregate.
Zamalek are looking to end their lengthy drought in Africa's elite club competition and win their first title since 2002.
They came close twice in 2016 and 2020 before losing to South Africa's Mamelodi Sundowns and local archrivals Ahly in the final respectively.
