I'm creating a flow to notify members of a Slack channel whenever a Box file in a folder is modified. However, when I wrote "@channel Please see the updated files." in the Post message element, I get the error message:
"The input parameter(s) of operation 'Post_message_(V2)' contains invalid expression(s). Fix invalid expression(s) for the input parameter(s) of operation 'Post_message_(V2)'."
Is there a valid expression for tagging channel members like this and if so, what is it?
