I need to do custom validation in a slack modal window.
The logic is that I first open the modal window with one input field, then update the window with other fields depending on the selection in that field.
When I click submit, I want to update the modal window with errors, if any. Otherwise the data should be submitted.

I am trying to get devices from Hexnode and restart specific devices via the button, but I am getting the error “This app is not configured to handle interactive responses…” when pressing a restart button.
