Hi, welcome to using Cesium.

The issue is that you are passing a Promise<Cesium3DTileset> to primitives.add instead of a Cesium3DTileset. createOsmBuildingsAsync returns an promise so you will need to use await or then to get the tileset from it.

See this example sandcastle which loads the tileset.

I have also moved this to the CesiumJS category since this is more closely related to the CesiumJS Viewer instead of the Cesium ion hosting service.
