Accept .license files

Hello

I want my own plugin to accept the .license file I created and authenticate it or the plugin will not work.
Currently the rhp file works without the license file.
I want the plugin to reject it without the .license file first.
For example
I want the user to see

“Activation is not complete.”

when they click on any of the commands.
Then, when the user clicks on

“License Activate”

, I would like to display a dialog and have it read the .license file.

best regards.

You might want to start by looking at the RhinoCommon OpenFileDialog:

I understand that, but it is not a targeted answer to my question.
