Does anyone have any recommendations for waterproofing the M0166 camera lens for light rain (not submersion) or dew? Or does the lens come with an internal gasket that causes that to be unnecessary?

We are wanting to use our drone in a field which may have tall grasses that could contain dew. It also may start raining and we want to waterproof the drone good enough to handle a couple minutes of light rain before we are able to get it to safety. Does anyone have any recommendations on that primarily for the camera optics part?
