International flights from Lima

Hi! My peruanian partner will travel to Germany from Lima in November by LATAM. We don't know if it is mandatory for her to present a acutal Covid-19 test for leaving Peru - i.e. for checkin and boarding the plane.

PS. The website of the international airport Lima and of LATAM is not mentioning that. The LATAM/LAN-Hotline ist not providing useful information.
