New road name + renumber of houses in Walhain / Belgium

Hello,
Our municipality has changed the name of a street and renumbered it. (1457 - Walhain - Belgium)
I tried to do it, but I don’t have access to all the change options.
For anyone who wants to help me, the part of the former “Place St-Vincent” becomes “Rue de la Couverterie” and starts from the line on the map, separating it from Place St-Vincent.
The house numbers are the same on the screenshot.
I’ve already made the changes on OpenStreetMap.
If needed, I have the official documents; I work in this administration ;o)
