Filter condition for outlook email subject in flow




My outlook emails have subject like this : SLA warning for INC1234567

                                                                  SLA warning for  INC2345678   etc...


My flow looks like this:

But this is an invalid expression.


How do i filter mails wrt the above different IDs?


Thank you.
