start an approval assigned to people field (multiselection) fails

hi...

i have an  approval workflow "when  a new item is created" that works fine if the manager field (assigned to) is a people field with no option to select more approvers.

if i change it to "allow multiple selection" than the flow fails.

it creates me an apply to each section that i do not need here.

how can i put the assigned to field on the start an approval section to an array or something that accept multiple email adresses?

thanks
