Save button does not work properly.

[lezuch]

We are not able to create new Slack notifications config.
When trying to save new config - nothing happens.
The Save button looks clicked, but the window won't close. So I need to refresh my browser.
After a few minutes config appears.
So saving a few times will make a few configs after a few minutes.

In TC logs, when clicking save, we have several:
INFO - jetbrains.buildServer.SERVER - Slack Integration - Requesting channels with cursor:

Plugin version v2.1.3
TC version 2020.2.3 (build 86002)

@alexkvak is there any update on this - It's happening on 2022.04.3 (build 108706) and caused the TeamCity server to slow down a lot as I spammed save as it wasn't working so it added multiple entries.

Has the work for this been dropped? This issue is still ongoing as of 2022.10.2 (build 117025)
