Overlap water rise on to a 360 video for virtual reality

Hello, I have filmed a 2 minute 360 video where the camera was placed stationary on a seat at a restaurant facing the ocean so that when it is viewed through a head mounted display the person feels like they are sitting in the seat at the restaurant. Over the course of the 2 minutes, I am wanting the ocean sea level to gradually rise. I was wondering if someone can recommend a good water package to purchase from the unity store and how I would go about overlaying it on the video so that the sea level gradually rises throughout the 2 minutes? (it is meant to be a 'time lapse' from now to 2050). It doesn't have to be overly realistic e.g., objects and people being washed away. Just the water completely covering everything it contacts would be fine. This is for a PhD in environmental psychology so I don't have a huge amount of unity/ VR experience. Thank you, Chloe,
