To create a duplicate for that Open the page collection ->SOW-Side bar Tabs Top
Open Record Information Page which you duplicated earlier or else OOB one, scroll down to the bottom on the left side until you found Caller Records Viewport
click on that and on the right side configuration you see something like below
