Saṇkhāra-cause, Saṇkhata-effect; So, we don't need to find that Where is Nibbana/Nirvana being Unconditioned stated in the Canon?

You can see these pali-words everywhere in canon. This is the reason that why I often told everyone to recite and memorize pali canon.
Saṇkhata (5 aggregate-effects) means it is caused, is conditioned, by 5 aggregate-causes.
Saṇkhāra (5 aggregate-causes) means it causes, conditions, 5 aggregate-effects.
Saṇkhāra-paṭiccasamuppāda (kamma-bhava, karma) means it causes, conditions, becoming (jāti, upatti-bhava, 5 khandha).
Asaṇkhata (nibbāna) means it is unconditioned by any saṇkhāra.
