Hi @rjmillerCAK
Once you use get items with filter query to filter out email addrees , you will get an output whether the form submitter is authorizer sender or not, so using the step below in your flow

does not make any sense as it will work when email addrees is autorized sender , as value contains only the email address.
To make it work , let's replace the above step with this below (making it simple )

in the condition we are checking this, whether the output / value dynamic content is having values in it or not.
if the above condition is true, then it means that submitter is non autorized person
if the above condition is false, then it means that submitter is autorized person.
condition expression:
length(outputs('Get_Email_of_Autorized_Agents')?['body/value'])
Hope it helps !
Mark it as solution if it resolves your query !
