How do I refresh a page with arg

In my app i display a list of items and each items have reviews.

When a user clicks on an item, it goes to the review page of the item and all the reviews are displayed.

In this view, when a user post a new review, how do i refresh the page so that the new review displays too or can I add the new review to the reviews object … if so how can it be done. I get the reviews via fetch
