Describe the problem/error/question
When using Slack Node with update method it ignores Message Type field set to “Block” and uses Notification Text field data instead data from Blocks field
What is the error message (if any)?
If Notification Text field is empty Slack API returns no_text which clearly shows usage of this field instead of Blocks field
