Alter plaintext through IV in block cipher AES in CBC mode

IV: 69bb375aa919c72aa561dd7b7ffacf66

Ciphertext: "c28ea025d10186510855d083747d6435c808d9857075abd9bfc54b094e60eaf3"

Plaintext: "SEND ENCRYPTED DATA"

I want to be able to change the resulting Plaintext to "SEND THE DATA", which if I understand correctly would involve altering the IV in this case.

I have read about the bit flipping and how this attack works, I am just having troubles implemeting it in this scenario, please help.
