Cypress code coverage of external custom angular module used in app component

I am using cypress for end to end testing. I wanted to get code coverage of angular component files which are being imported from custom angular packages we have created and deployed in dist folder, this imported package contains all the components, services, akita store and is being used in app component, routing. Currently cypress only covers code for ts files present in src folder which seems to be of no use as it does show coverage of actual components which were imported.
