@myWebmaster , when I tested, the Update operation actually replaces the “old” message with the new one and “Include Link to Workflow” option is not there indeed. However, as it is not there the update operation replaces the whole old message with the new one including the “Automated with this n8n workflow” string. In other words, it is removed automatically without the need to be explicit.
No issue with removing the footer on Sending a message, but even if the original message has the footer removed, upon the Update Message node updating it the footer is re-added without an option to remove it.
The Update Message node only has the additional options of:
Link User and Channel Names
Parse
Whereas the initial Send Message node for Slack has a lot more options, including:
Include Link to Workflow (This is the one that should be added to the Update node)
Custom Bot Profile Photo
Unfurl Links/Unfurl Media
And more. I understand a handful of these options don’t make sense on the Update Message node, but it is strange that the first 2 listed above are absent?
