Accurate Data Retrieval Using Message Path Syntax in Foxglove Extension Panel Development

[Kezunlong1025]

I am currently developing an extension panel for Foxglove, and I have utilized the Message path syntax. But how can I accurately retrieve the specific value of the variable that my Message path syntax points to within this extension panel? In other words, I have indicated the path, but how do I access the concrete data within the extension panel?
