Consulado General de Francia en Düsseldorf

Signature of "Convection d'Accueil d'un chercheur ou enseignant-chercheur entranger"
Hello
I write because I would like to ask about a paper that needs to be signed by the embassy because I will start working in February in Orleans, France.
I am Argentina but I am currently living in Germany, from the institution who hired me (the University of Orleans) they sent me a paper called ""Convection d'Accueil d'un chercheur ou enseignant-chercheur entranger" that needs to be signed by the French embassy .
My question is if I must request a appoiment to carry out this procedure or can I go directly, presenting this paper and my passport, is this enough?

Thank you for your answer

Best regards
