🚀 Feature Proposal

I have my custom way to handle errors depending on their type. I know that by using verifyBearerAuth there are 2 types of errors that can be thrown and I have a custom way to handle booth cases separately. But now I cannot check if the error is an FST_BEARER_AUTH_INVALID_AUTHORIZATION_HEADER or an FST_BEARER_AUTH_MISSING_AUTHORIZATION_HEADER because none of them is exported

Motivation

Handling errors a custom way.

Example

if(error instanceof FST_BEARER_AUTH_MISSING_AUTHORIZATION_HEADER) {
  // handle missing authorization header
} else if (error instance of FST_BEARER_AUTH_INVALID_AUTHORIZATION_HEADER) {
  // handle invalid token
} else {
 // Probably a 500 error or any you have defined
}
