switchboard & nDisplay

I am using various functions using switchboad and nDisplay.
Up to running the viewport used by nDisplay through the switchboard, not the other part, was successful.

However, I want to output the nDisplay screen by executing the packaged exe file on the switchboard.

I put uproject in the switchboard setting, put nDisplay config, and saw that EngineEditor.exe was connected to the setting.

I don’t know if it’s the right way, but I removed uproject, replaced EngineEditor.exe with the exe I packaged, and copied plugins and other error handling necessary for engine installed on the engine to solve various errors and distributed them appropriately in the build folder.

However, the exe is executed through the switchboard, but the output is as if the player was pawned, not the camera applied by nDisplay.
Do you have any idea how to run the packaged nDisplay project via swtichboard?
