Elastic APM RUM angular 0.4.1 - Code Autocompletion

Hi,

Just to keep in short, upon installing elastic-rum-angular-0.4.1 in my project. I am not getting autocompletion of code in my intellij IDE. I did add following in my tsconfig.json, still no luck. Can some one help me about this. Thanks in advance.

   "types": [
      "@elastic/apm-rum-angular"
    ],

I also tried by adding the following in tsconfig.json

   "types": [
      "@elastic/apm-rum"
    ],
