IBackgroundProcess is registered in DI but IBackgroundProcessAsync is not

[chr-papadopouloskaizen]

There isn't much documentation on the usage of IBackgroundProcess , https://www.hangfire.io/overview.html#background-process.
There are closed issues on this as well.

I saw that you can pass the job on UseHangfireServer, but IBackgroundProcessAsync cannot be used like this.
Is there a recommended way of using IBackgroundProcessAsync ?
