Attach plugin to right panel after show

When I create a panel and show them I want this panel will be attached to the right panel in a photoshop


How I can do this?

There is currently no mechanism to specify where you’d like to be docked; the user has full control over this. If Ps is open when your plugin is installed, it’ll show in the upper-left corner, and the user can dock the plane to wherever they’d like.
