I'm trying to acknowledge receipt of an email with an SMS.
Currently testing so looking to strip out the telephone number from the Subject of the email & SMS the formatted number in the body of an SMS to a fixed target. When proven to work, I want to use the formula to generate the target for the SMS.
I've tested the formula works using a flow to create an entry in a sharepoint list. I just don't need the sharepoint list.

How can I force the connector to evaluate the formula rather than treating it as static text?
Thanks in advance.
