New directory for the Tielsets. Simple way to update the map?

Workadventure makes a change from webpack to vite and from map.json to map.tmj. This is accompanied by a new directory structure.
I have copied my tilesets to the new directory. Now when I call the map.json the tilesets are of course not found
Is there a way to point to the new directory?
or do I have to rebuild the map completely?

When you open a map in Tiled and it can’t find the tilesets or tileset images, it’ll prompt you to locate them, so you don’t need to rebuild the map.

Danke für den Tipp.
Thak you for this hint
