configuring cors for my node.js server

We have node.js server running properly in http://localhost:4200 (with Angular 6). Now I use ngrok tunnel to make my website go live (i.e. [login to view URL]), but while Angular components still seems to work fine, node.js access return "ERROR_CONNECTION_REFUSED" on Chrome browser and "Cross-Origin Request Blocked" in Firefox (Please see attached pictures).

Therefore, I need help configuring Cors in my node.js project's [login to view URL] file. to make it works properly when connect from ngrok domain (i.e. [login to view URL])

Thank you.
