First African American kpop girl group member not even in the video?

RANIA's "Demonstrate" came out yesterday and frankly I am very confused. Firstly, why was Alexandra Reid nowhere to be found in the actual music video? Throughout the teaser she was shown quite a lot, but even then everytime she was depicted she was in black and white. Is there a reason for this? Are they not ready to debut her yet? What do you guys think?????

loveeeee kpop and everything Korean. Need more language skills though
