Change the target of inspector from script

Hi everyone,

In the inspector, when we double-click on a prefab/asset field, it changes the target to that asset. Is there a way to it programmatically? I tried changing Selection.activeObject but doesn't seem to work.

p.s. I'm writing a node editor, it edits a Canvas asset which contains all nodes as subassets. When a node is selected I want the inspector to focus on that specific node.

Thank you!
