Error EntityManager#remove() expects parameter 1 to be an entity object, array given. - how to fix?

Question

symfony

Good afternoon, I'm new to symphony 4 - please help me figure out what's wrong.
I'm trying to delete a user from the intermediate table, this is what I have in twig:
(for some reason I can not display the twig code correctly, so the screenshot)

Next, in the controller I have this
/**
* @Route("/deletion", name= "deletion")
*/
public function delete() {
$deleteUser = $this->getDoctrine()->getRepository(EvaluationUser::class)->findBy($_POST);
dump($deleteUser); // die;
$em = $this->getDoctrine()->getManager();
$em->remove($deleteUser);
$em->flush();
As a result, if I dump-give $deleteUser - in the dump I have everything I need - both idUser and idEvaluation
When I try to put the final point (remove + flush) - an error ...
Many thanks for any ideas in advance.

If you assume that one entity will come, then get the object correctly:
Otherwise, you get an array with one element
