Open new record from process

Dear,

I have add a button on the contact page in order to create an opportunity :

When you click on "Créer une opportunité" it launch a process which open a preconfigured page, the user select the "Besoin client" and then click save. Next i'd like to open the new record.

So in my process :

the opportunity page opens but it closes automatically.

how to keep the page open?

Thank you !
Nicolas
