Join failed with 1.7.0 web sdk

Yes, I am in China.
after I open web access feature, I can join through zoom’s web url successfully.

I have tried “ZoomMtg.setZoomJSLib(‘https://jssdk.zoomus.cn/1.7.0/lib’, ‘/av’)” ,it’s still failed.
I try local library through:
ZoomMtg.setZoomJSLib(‘http://localhost:9999/node_modules/@zoomus/websdk/dist/lib’, ‘/av’);
but I still get failed.
I guess the root cause is my account is trial,and in china system force to verify Phone SMS. If this leads to failure.
