trigger at one page reflect in other

[pranavp10]

Hi all ,
i just wanted to know can a trigger works when called from one page and it should reflect in the other page,
here is the example
page1 (http://localhost:3000/addname)
page2 (http://localhost:3000/displayName)

In page1 i don't mutate here just a api call to add to database if success then i trigger eg(trigger(key) of page2) will it reflect the changes in the page 2
in page2 it will only display names it will be only trigger when a new name is add at page1

will it do a api call onse i call the trigger
