The noun 'der Einwand' (objection) comes from the verb 'einwenden' (to object). When someone 'einwendet' (objects to something), they express an objection. This connection helps you understand its meaning as a counterargument.
Der Anwalt wollte etwas einwenden, aber der Richter ließ es nicht zu.
The lawyer wanted to object, but the judge did not allow it.
'Einwand' is often combined with certain verbs. You can 'have' an objection, 'raise' one, or, in more formal contexts, 'erheben' (raise/lodge) one.
Ich möchte einen Einwand gegen die geplante Änderung vorbringen.
I would like to raise an objection to the planned change.
When you want to say what an objection is directed against, use the preposition 'gegen' (against) followed by the accusative.

approval / consent
'die Zustimmung' and 'der Einwand' are opposites when it comes to a proposal or plan. With 'Zustimmung' (approval / consent), someone shows that they agree. An 'Einwand' is a counterargument or concern raised against something. An 'Einwand' is usually not as formal as an 'Einspruch' (formal objection), but fits well in meetings, conversations, or discussions. If no one sees a problem, there is 'Zustimmung'. If someone gives a reason against it, they raise an 'Einwand'.
