Office Add-In using VsCode and Mkcert Private Trusted CA

Introduction Developing of Office add-ins requires use of HTTPS. SSL/TLS certificates are therefore required to grant permission to use encrypted communications and authenticate the identity of the certificate holder. When a new add-in project is generated, self signed certificates are also created for the project. For browsers to use these certificates, they have to be added as trusted root certificates. There are times however that some browsers fail to recognize these self-signed certificates as trusted even after adding them as root trusted.
