I can filter the table with an external action "Filter Array":
@And(not(equals(item()?['Project_x0020_Requestor_x0020_(OU)'], 'Materials North America')), not(equals(item()?['Project_x0020_Requestor_x0020_(OU)'], 'Materials Processing & Services North America')))
now how can i extract a column out of this filtered array/table into an array?
Like after filtering out project with the condition i mentioned now i get a reduced table and out of it i want to extract the column "Project Manager" to get their names into an array.

Trying the above mention method i get the following error:
The 'from' property value in the 'select' action inputs is of type 'String'. The value must be an array.
