Hello and welcome @Anton_Montagne
I had difficulty understanding your post until I watched a couple of Pulsonix “how to” videos.
Pulsonix selection starts with the component (data sheet) followed by the footprint and lastly the symbol.
Kicad selection starts with the symbol and is followed by the footprint and data sheet.
The end result seems to be the same for both products: you have a component with a matching symbol and footprint.
