Does look like above the mirror would work on yours, but on the passenger side the mirror is further from the glass, so harder to see over/under, you might need to swap the two cameras.
Location does depend a bit on if you want it looking rearward normally or always looking towards the driver's door to some extent, in which case it is less likely to be blocked by the mirror.
But every car is different, just need to try it, with the live view running on the app.
On the two vehicles I've tried, it happily went under the mirror, although on my car it was then blocking the view of the A129 and A139 I had above it, so I moved it to the bottom of the glass, where it was surprisingly out of view of the other two. Not a recommended location, but it does work. Neither vehicle had a significant sensor pod though, just a small one for auto wipers.
