Set Worker count for Hangfire (MassTransit version 8)

[DronLee]

Hello everyone! I faced with one problem after moving of MassTransit packages to version 8.1.3 from version 7.3.1.
I used method UseHangfireScheduler with setting WorkerCount. Now the method is Obsolete and it's proposed to use AddHangfireConsumers and AddHangfire. Both this methods dont't allow to set WorkerCount, and when I start my application I see in application logs "Worker count: 20". It's too much for me! How I can set less value?

AddHangfireServer has the WorkerCount configuration.

Yes, I know. I tried it. If I use AddHangfireServer(options => options.WorkerCount = 1) and then AddHangfireConsumers(), I receive two records in application logs:
Using the following options for Hangfire Server:
Worker count: 1
and
Using the following options for Hangfire Server:
Worker count: 20

I reckon it's strange.
If I delete AddHangfireConsumers() my application is compiled, I don't receive any exceptions, I see only one record in application logs "Worker count: 1", but my scheduled message is sent never.
What am I doing wrong?

Might be related to this unfortunately:

MassTransit/src/Scheduling/MassTransit.HangfireIntegration/HangfireIntegration/HangfireBusObserver.cs

Line 45 in fd316e0

_server = new BackgroundJobServer(options, _jobStorage);

So you can use

services.AddOptions<BackgroundJobServerOptions>()
    .Configure(options => options.WorkerCount = 1);
