Invoke function of CEP Panel from another CEP Panel

Hi,

I have two CEP panels running in Adobe Premiere Pro. I would like to invoke a function of Panel_2 by a button click in Panel_1. The function of Panel_2, which is subject to get triggered, would update the UI in Panel_2.

Has somebody experience in doing this?

Maybe a customized event which is shared between both panels, BridgeTalk or a csInterface-Function could work?

Could you please provide a code sample?

Thanks in advance.
