// Connect, using the token we got.
this.connection = new signalR.HubConnectionBuilder()
    .withUrl("/hubs/chat", { accessTokenFactory: () => this.loginToken })
    .build();

The server validates the token and uses it to identify the user. This validation is done only when the connection is established. During the life of the connection, the server doesn't automatically revalidate to check for token revocation.
