Fail to include toolbar for latest Context capture cesium export

Hi everyone.
I am new in Cesium, i have this Cesium application exported by context capture with different version.
I normally export the 3d model from CC and load it from my desktop as server.
in the recent update CC v17 only have viewing capability, they omit the measurement tools

V17 with V15 toolbar -

I try to use the tools in CC15 and load the cesium model exported by CC 17. but no 3d model is loaded.
appreciate your help. the file are attached in link

Hi @Yihao_Ng - welcome to the community forum! Which of the files in the drive folder are you having trouble with? Are you loading them as Model objects?
