Any event to confirm all tiles are visible in current extent?

Hi everyone,
Is there any cesium tileset event that confirms all tiles are visible in the current extent or viewport?
Like I want to render new york city buildings from photorealistic 3dtiles in Cesium viewer. So, I need to confirm all buildings are visible in the viewport.

Can anyone help me?

Thanks in advance.

Hi @Masum_Billah,

Try Cesium3DTileset.allTilesLoaded.
