I need to create a flow where when I attach an Excel file to a specific group, a private message is sent to the users listed in the file.
The file is composed of (Column "A": User's full name; Column "B": Messages to be sent).
I'm having trouble extracting the name from column "A" and transforming it into a user ID to send the message privately, because the flow loops and doesn't trigger the message to the users.
Can you help me with a way to extract the names and transform them into Teams User IDs?
