How can I force a Portal Entity View to refresh to display the dataI have just changed.

In the image above the entity is updated via a HTML call (triggered by a button on the page) to trigger a flow that sends an email. During that process the entity updates the Email Sent field to Yes from No. It take 15 minutes to update after refreshing the web page. How can I force this to be quicker, i.e. when then triggered flow is completed?
