Changing access token during SignalR session (with websockets protocol)

The following phrase is emphasized on https://docs.microsoft.com/en-us/aspnet/core/signalr/authn-and-authz?view=aspnetcore-2.2:

> The access token function you provide is called before **every** HTTP request made by SignalR. If you need to renew the token in order to keep the connection active (because it may expire during the connection), do so from within this function and return the updated token.

However it's easy to confuse 'http request' here with the concept of 'message sent'.

When using websockets there is only *one* http request made when you first connect - after that the token isn't sent again and my function isn't called. The above paragraph kind of implies it will automagically refresh itself when it changes which for websockets isn't entirely accurate.

Can you make it clearer what the recommended procedure is for changing access token when connected with websockets. I assume I'm supposed to just disconnect and reconnect.

Although to be frank this is kind of a massive pain and I'm almost tempted to just send the access token as part of the message (which in my case is rarely needed anyway).
