How to use the 'Robot Framework' to load files using a custom keyword

@Dave_Evers thank you so much, it works partially. It comes up but cant find the file then it does not click it to add it…

It writes the path in the FILE name field however it it does not double click or select it when it finds it…

I need it to click OPEN in file explorer or double click it so it automatically gets added, Once it does that after finding the file , it will work.
