Using REST interface for async updates

[deepak079]

Hi Bryant,
Thank you for all your hard work on this project. I need a little help in using an exchange's REST interface to poll candles' data.
In the README page you have mentioned that we can use this library to poll REST endpoints. By that did you mean there's already a method in the library to do that? Or does that mean we'll have to write async code to use an exchange's REST methods that's available with this library.
In the examples directory I found code where you have used FTX's REST method to download historical data. What I am looking for though is to use FTX's REST methods to get realtime candles' data. Can you point me to an example if there's one on how to do that using cryptofeed? If it's not there can you provide me some code/advise to accomplish that?
TIA
