Support plain-text @mentions using raw user ID formatting for MS Teams
When posting to the Slack from Smartsheet automation, it is possible to use <@{Slack_ID}> format in a plain-text message to mention either users or channels through a Slack app or webhook with appropriate permissions, Slack recognizes the ID and turns it into a true @mention . This works because Slack allows plain-text message formatting that includes raw user ID strings and interprets them correctly when sent through authorized apps or integrations.
In contrary to Slack, Teams requires a structured message format using its API, and now user mentions are not triggered in Teams channels through Smartsheet automation. It is necessary to develop and implement the same capability for mentioning members and channels in MS Teams using native "Alert Someone → Send to Microsoft Teams" Smartsheet automation.
