Programmatically create desklet instance ?

[gadlol]

Hello.

I have created a Desklet with the option to have multiple instances.

I need a way to right click on an image or on a file and create an instance of the desklet and use the file path to a setting in the configuration.

Is it possible?

I know that I may need to add a script in ./local/share/nemo/scripts but the first thing is to know how to create an instance programmatically.

P.S. Why there is not enough documentation on the internet about desklets development and not many examples?
