Plugin gain reduction

Hi,

I am developing mini cross platform VST3 host.
I want to display plugins gain reduction inside the host,
Is there an API with which I can get the information from a plugin ?

Thanks

See https://developer.steinberg.help/display/VST/[3.7.0]+Parameter+Function+Name. This is new with VST SDK 3.7 so to find a plug-in supporting this may be difficult.
