If it was mine, and not understanding how this design of glass is made and now failing.....I’d mask it off and paint the surface with high gloss black paint, on one side or the other.
It was never designed to be clear glass to see inside anyway.
Not sure where the defect is.....inside or outside glass?
As far as removing it....it’s probably in place with just silicone or such, so a box cutter blade to start.
