Although the Green's function of the Klein-Gordon equation is given (precomputed as an example) on the DiracDelta and HeavisideTheta functions documentation pages, Mathematica 11.3 is itself incapable of calculating it with its own GreenFunction.

Can somebody confirm this?

This seems odd, since all Green's functions for other common equations are present and, presumably, hard coded.

Am I missing something?
