Currently I cannot find a way to know for which channel has been configured an incoming webhook (in my case, for integration with GitLab).

In the "Integrations/Incoming Webhooks" section, just appear the name of the webhook and the webhook URL it self, without saying for which channel has been set, and the option of deleting it. And in the GitLab side there's no way to know for which channel will be triggered the hook.

This come become a problem when you have several webhooks and channels.
