I am trying to use react-google-charts in my forge app and i am facing this issue where i am not able to load the chart the error i am recieving is 

loader.js:131 Refused to load the script 'https://www.gstatic.com/charts/51/loader.js' because it violates the following Content Security Policy directive: "script-src 'self' 

I have added 

permissions:
