When a new email arrives (V3); using different email address compared to the creator of the flow,

I have a service account named SharePointDev and a service account named SharePointDevTest. now using the SharePointDev account i created a flow >> and i defined the SharePointDevTest inside the To field. but when an email get sent to SharePointDevTest the trigger will never get triggered.. any advice?

while if i create a flow using the SharePointDev and i also defined the To field to be SharePointDev the trigger will get executed.

Thanks
