Is there any way to evaluate (or even plot) the inverse survival function of a sum of two Fs?

Here is what I have so far

\[ScriptCapitalD]=TransformedDistribution[u+v,{u\[Distributed]FRatioDistribution[2,2 2],v\[Distributed]FRatioDistribution[2,2 2]}]





All above commands return the results I expect but when I try

Plot[InverseSurvivalFunction[\[ScriptCapitalD],x],{x,0,1},Filling->Axis,PlotRange-> Full]

Mathematica won't show any curve. Does it mean that Mathematica could not find an expression for it?

I know that the sum of Fs will get rather complicated.

Is there any way to get an output from InverseSurvivalFunction[\[ScriptCapitalD],0.95] for instance?

Many thanks
