How she made this tiktok video?

I know her name is Hazel aka Babyfacedhoe. I found this on reddit also on redgifs. All I want to know is, how did she make this? In the picture you can see that a mirror is moving and her body getting exposed, how she did that? It seems it’s a filter of tiktok but It's not, in tiktok there's no filter like that and besides tiktok never allows, nudity, pornography. She used another app or software or platform and used tiktok to add the music only. So Which app or software she used to make the video? If you know please help me. I need to know
