How To Sent Program Change To Vst?

How do I sent a Program change to a VST effect?
I know for VST instruments I have to type M2 but how about effects?

Use an Fx Alias from that effect in the VST instrument list?

It doesn’t work with jBridged plugins though i noticed…

That’s it, so should this be filed as Bug?

EDIT: doesn’t seem to work with native effects also
