I cloned [this](https://github.com/zoom/zoomapps-advancedsample-react) branch and did all the things as described in readme file but when I am trying to install the app nothing is opening into the app inside zoom client and in the backend logs it’s showing 304 with the same URL I am trying in browser it’s responding with 200 but we can’t use that sdk in external browser ---

Zoom Apps SDK is used to interact with your Zoom native application from Zoom App. You cannot use it in external browser. Can you paste errors from your docker and console? ---
