ESP32 WebSocketsServer - stream pots output to web browser

I would like to stream pots data to a web browser using websockets. I'm using WebSocketsServer on a Huzzah but sendTXT isn't working, but does for Connected WStype. Is there a way to do this?

void loop() {

int potValue =analogRead(A4);


//delay(1000); //adding a delay slows connection times dramatically ;-(



Doesn't anybody stream data to a client? How is it done with WebSocketsServer??
