I have a Google Cloud Function written in nodejs, which I want to run with @google-cloud/functions-framework. My structure is

main_folder/ 
 test_function/ 
   index.js 
 node_modules/ 
 package.json

So as in the structure, my entry point is inside test_function/index.js. Is there a way to call that function using function framework ? or function framework does not work with folder structure (index.js has to be in the root folder) ?

Any help would be appreciated. Thanks in advance
