I want to post an "ephemeral" message to a user after a modal is submitted via a global shortcut. But in Slack, global shortcuts don't have the context of the channel the user had focused when the shortcut was invoked. The API body on the interactivity endpoint doesn't contain any channel information.
Yet there is this example from the Asana shortcut:
How are they able to respond with an ephemeral message to the channel that the user had focused when they invoked the global shortcut?
