I am trying to implement the Token Credential authentication added here: tediousjs/tedious#1641

For some reason I am getting a TypeError: The "config.authentication.options.credential" property must be an instance of the token credential class error when trying to connect.

My authentication object in the config looks like

authentication: {
 type: 'token-credential',
 options: {
 credential,
 },
}

where credential is a new ClientSecretCredential from @azure/identity. If I call isTokenCredential(credential), it returns true. So I'm not sure why I am hitting this error.

Here is the line of code where the error occurs: https://github.com/tediousjs/tedious/blob/master/src/connection.ts#L1139
