SoundEffectSourcePresetChain class variable "chain" is not accessible in Blueprint

As per the documentation (unreal.SoundEffectSourcePresetChain — Unreal Python 4.26 (Experimental) documentation):

SoundEffectSourcePresetChain class has a public variable “chain”.
But this is not accessible in Blueprint.

Please share the steps to access this variable in Blueprint.

Thank you.

I believe it would involve rebuilding the engine from source.

Unless you are looking for this?

When you right-click and search for a node try clicking on the context-sensitive checkbox. Otherwise, I think you need to write some C++ code and build from source.
